The weights can end up sinking into the Earth, see the screen shot below. To duplicate:

1. Load the sim
2. Switch to the chambered pool with the weights
3. Put all weights into the pool
4. Press the reset button (will switch back to square pool)
5. Select the chambered pool with the weights again

The question mark on the mystery screen should disappear when the box is closed, rather than staying in the dirt.

When "Grid" is selected, we now see that the text runs over the grey concrete barrier of the pool. This should be moved to the left slightly so that it no longer overlaps.

On the other scenes, there is a green box with rounded corners which says "3 meters". To conserve space, this should be changed to "3m". On the third scene, the green box should be moved such that it doesn't block the view of the faucet.

To duplicate:

1. Load the sim
2. Put a pressure gauge in the pool before any fluid exists
3. Add fluid. Reading of the pressure gauge doesn't change.

Screen shot (illustrates test case):

See screenshots below that show how it looks in Firefox (which is where it is a bit off) and how it looks in Chrome (where it is fine).

See screenshot below which compares the panels. Rounded corner radius should be the same.

Problem description:
The question mark appears on the first screen in the fluid density box instead of the density slider.

Steps to reproduce:

1. Open the sim and click on the mystery screen.
2. Select the mystery planet option then hit the reset all button.
3. This will return you to the first screen, with the question mark appearing in the fluid density box.

Severity: Medium, makes it impossible to change the fluid density until a different screen is selected

When the Fluid Density and Gravity panels are closed, the text should not be touching the bottom edge of the box. See screenshot below.

When closed, a few pixels could be added to the top and bottom to avoid looking cramped.

Since this is on a surface it is not high priority.

When selecting the faucet knob or sliders, there is a delay before the sim responds - I would estimate in the delay to be about .25 seconds - not enough to make the sim unusable, but certainly noticable.

Version: http://www.colorado.edu/physics/phet/dev/html/under-pressure/1.0.0-dev.1/under-pressure_en.html

Upon loading or switching pools, the pools are empty. They should have something in them, as shown in the design document and as they do in the original Java simulation.

They also don't quite match the look of the scene when you select it. This issue might be best addressed toward the end of redesigns as we would then take higher resolution screenshots of the different scenes when they are in there final version.

There is no boundary for the locations that the pressure gauges can be placed. If you click and drag a pressure gauge in any direction until your mouse leaves the web browser window, the pressure gauge will leave the screen and you can no longer access it.
Tested 1.0.0-rc.1
Mac OSX 10.9 with latest chrome.

When the grid is turned on, it protrudes beyond the edges of the pool and below the controls for the 2nd and 3rd pool configurations. This looks a bit odd, and it has been requested that the grid be bound to the edges of the pool. The described behavior can be seen on this version: http://www.colorado.edu/physics/phet/dev/html/under-pressure/1.0.0-rc.2/under-pressure_en.html

Once a pressure meter has been removed from the control panel, it can't be put back. This behavior can be seen on this version:

http://www.colorado.edu/physics/phet/dev/html/under-pressure/1.0.0-dev.1/under-pressure_en.html

Screen shot after pulling out the meter and then trying to put it back:

The right ticker in the gravity panel seems to be the only one which does not gray out when the slider is all the way to the right.

"PhET" icon is not displayed in the lower right hand corner for Internet Explorer 11. Tested on Windows 7 with the latest version of Internet Explorer(11.0.9600.16518)

The color of the fluid coming out of the faucet should more closely match the color of the fluid in the tank. The fluid coming from the faucet seems darker even than the bottom of the tank, which is the darkest given the gradient.

See the screen shot for a look at how the control panels appear when the term 'Mystery Planet' is translated into Macedonian. The panel should get wider to accommodate the contents, and should stay centered above the lower panels. The barometer box should move left or right in response.

The pressure gauge behavior when in the ground should be slightly different. Namely, there should be no needle, and no box around the dash. See attached screenshot.

When you use the faucets the text within the tool box in the upper right hand side with (ruler, grid, atmosphere, units, metric, atmospheres, english) translates left and right very slightly. Particularly the spacing of letters increases and decreases as you add or remove fluid.

Tested on a Windows 7 Enterprise 32-bit, on Firefox 27.0

The gauge needle/handle is very difficult to see when the background is light. A gradient should be applied such that it is darker and easier to see.

Current HTML5 needle

Needle in mock up

Neither the gravity box nor the numbers for fluid density loaded on the iPad mini, even after multiple refreshes.This didn't happen on an iPad 2 or iPad 3.

Pressure gauges don't update when switching between the first and second screens. See screenshots for examples. The first example shows the gauge reading pressure when it is in the ground, while the second example shows no pressure reading in the water. This can be reproduced by simply placing a gauge anywhere on one of the screens, then switching to the other without moving the gauge (this only happens between the first and second screens). I should also note that this only happens when the levels of fluid are NOT changed.

Example 1: Screen one to two

Example 2: Screen two to one

Changing the fluid density and/or gravity on any of the first three screens then switching to the mystery screen and pressing the reset all button does not actually reset the fluid density or gravity.

When the ruler is selected, the zero position should be lined up with the top of the tank. The ruler in the current HTML5 version is not lined up.

There should also be a red "X" at the top left of the ruler so the user may remove it without having to click on the check box again.

Mystery Fluid and Mystery Planet Details

The fourth screen will contain three mystery fluids (different densities) and three mystery planets (different accelerations of gravity). This scene will be different from the other scenes in the following ways:

A new box will be added underneath the box containing units - see the mockups below

. This box will contain two radio buttons allowing the user to toggle between having a mystery planet and a mystery fluid

A new drop down menu will appear in the dirt between the pool and the fluid density box. When the “mystery planet” radio button is selected, the options in the drop down menu should be “Planet A”, “Planet B” and “Planet C”. The values of the accelerations (in m/s^2) should be 6.5, 14 and 20 respectively.

When the “Mystery Fluid” radio button is selected, the options in the drop down menu should be “Fluid A”, “Fluid B” and “Fluid C”. The values of the densities (in kg/m^3) should be 765, 880 and 1,300 respectively. Below are examples of the colors for the mystery fluids.

Lastly, we recognize that the above details regarding the mystery scene were added late, and so please be sure to update the development cost.

If you take a pressure measuring device and bring it to the surface of the fluid, at a slight distance away the pressure changes as if it were in the liquid without the pressure measuring device being in a liquid.
This issue is displayed in the image below. Note that the pressure measuring device on the left is level with the one on the right. Happens with the variety of changes in fluid density and gravity.
Tested on OSX 10.9 dev.5

This sim is nearing completion, so it's time for PhET to do a code review. This ticket will be used to track general comments and as the issue for which commits can be logged against.

Comments in the code will be marked with either //REVIEW or //DOC.

Using the slider to change gravity works just fine, but clicking on the arrows doesn't change the numerical value shown for gravity, nor does it update the pressure gauges.
Additionally, if the gravity arrows are clicked a few times on any of the first three screens then the sim is switched to the mystery screen and the reset all button is pressed, the sim doesn't return to the first screen and things like this happen when trying to change screens (also notice how the numerical value and position of the slider for gravity don't match):

Need to add @gruneich as well as the MLL sentence.

Excerpt of email from @ariel-phet:

In scenes 1 and 4, with the grid on and "metric" could we adjust the "1 meter" so it aligns with the other numbers, the string is obviously a bit shorter since it is "1 meter" and not "1 meters"? Alternatively each of these could be "0 m, 1 m" etc... The more I look at it, I am fine with the abbreviations for "m" and "ft". Seems like it would be cleaner and more consistent all around.

Zero pressure

Max pressure

The gauge should have a maximum which does not wrap all the way around. I think the needle position at zero pressure could be rotated further counter-clockwise than it is now. Then, the max pressure could be placed at the position reflected about the y-axis.

Test device: Lenovo Z585

Operating System: Windows 8 64-bit

Browser: Firefox, Chrome, IE10 (only slightly)

Problem description: The weights on the third screen can cover each other and make it difficult to see all of them.

Steps to reproduce:

1. Open the sim and select the third screen with the weights.
2. Place both the 250g weights in first followed lastly by the 500g weight. Wait for the weights to stop moving.
3. Click the 500g weight, releasing it quickly. This part may be tricky to reproduce. Just try to pick up the 500g weight and place it back immediately, before the two 250g weights have time to rise back up.

Severity: Low, the water still acts correctly.

The ground and the upper faucet need to extend further to the left and right sides. The problem can be seen in this version: http://www.colorado.edu/physics/phet/dev/html/under-pressure/1.0.0-dev.1/under-pressure_en.html

On the second scene, there is a portion of the lining of the pool which is drawn behind the fluid, unlike the other scenes and the rest of the lining on this scene. The boundaries of the fluid/pool lining should be redrawn such that the behavior is the same for all parts of the pool lining.

When the needles of pressure gauges are placed anywhere below the red line (see screenshots) and the reset all button is pressed, the gauges return to their box incorrectly. The red line applies to any screen and is in the same position.

After resetting:

The 2nd and 3rd pool grids have 1/2 meter resolution. This is consistent with the Java sim, but is a bit odd. The original developer of the Java sim doesn't recall why it was done this way, so for consistency, the grids should all have 1 meter resolution.

It is currently aligned on the left, but is not wide enough and so does not line up on the right. Both right and left edges of the boxes should be aligned.

The design team has requested that labels be added to the grid for the 2nd and 3rd pool configuration.

This problem exists on this snapshot:

http://www.colorado.edu/physics/phet/dev/html/under-pressure/1.0.0-dev.3/under-pressure_en.html

The Fluid Density panel can end up with a question mark on it for the first pool after a reset occurs (see screen shot below). The steps to reproduce are:

• Launch sim
• Switch to the mystery pool
• Select the "Mystery Planet" option.
• Press the Reset button

The result looks like this:

In the mockups, the fluid density slider is on top, but it is reversed in the last dev version.

On the second scene, a portion of the faucet has been cut off due to the angle of the tank.

This should be changed such that all of the features of the faucet are visible.

In IE11, after opening the sim for the first time, the word "Pressure" disappears from the top pressure gauge (so additional gauges dragged from the pile will look correct) and the word "Density" or the word "Fluid" in the Fluid Density box disappears (it was not consistently one or the other that went away for me). Furthermore, the words "Under Pressure" along the menu bar at the bottom leave. It should also be noted for those trying to reproduce that sometimes it takes a few seconds before anything goes missing. This issue is easily fixed by refreshing the tab (in the browser, not the reset all button) and reloading the sim, but will continue to appear every time it is opened for the first time in a browser. Seen on a Windows 8 64-bit Lenovo Z585 laptop and 1.0.0-rc.4.
Also: #42 is also present, where the PhET icon is missing. I'm assuming this is related.

After the level of fluid in the mystery scene is changed (by adding or draining), the level doesn't revert to default after the reset all button is pressed.

After resetting:

Test device: Lenovo Z585

Operating System: Windows 8 64-bit

Browser: Firefox

Problem description: When a different tab in the browser is left open for long enough and the sim is returned to, the weights and water "fly" off screen (see screenshot). Occasionally the weights return.

Steps to reproduce:

1. After opening the sim, switch to the third screen with the weights and place any amount of weights into the water.
   2.Open another tab in your browser and switch to it and stay on it for about 45sec-1min.
2. Switch back to the sim tab.

Severity: High, this is incorrect physics after all

Drag the max number of pressure gauges out of the control panel, then press the reset button. Gauges stay where they are.

On the mystery pool scene, if you switch between Mystery Fluid and Mystery Planet it reveals the fluid density for you. Similarly flipping between these reveals the mystery gravity. It seems that when these radio buttons are toggled the gravity should always return to the Earth value, and the density should always return to the water value. Not sure how deep the code needs to be dug into to fix the issue.
