This scene does not accurately replicate the experiment in the article. A large, heavy ball is lowered into the water HALF-WAY, so that the upper half of the ball is above the level of the water. The question is, what happens to the combined weight of the container, the water, and the ball, compared to the weight of just the container and the water?

I guess it really is the worst Marble Race because the marbles do not move!

I've seen a similar after-market trigger that can be installed on an AR-15 that gives a 3-round burst. I'm not sure if it is legal here in the U.S. because it converts the semi-auto rifle into full-auto (3 rounds for each trigger pull).

Why do you claim this scene is yours? It was made by lololoer!

The scene is a great idea, but as you mentioned, the rope occasionally goes crazy and flips the entire machine in the air! But even before the rope went ballistic, I was not able to figure out how to make a 3D object with the controls that you specified. Can you maybe give more details? Thanks!

EDIT: I tried many different settings for the rope, and I was not able to stop it from "exploding". Maybe a better way to make a MakerBot 3D printer would be to spawn water from a nozzle and then have it freeze as soon as it touches the surface of the moving X/Y/Z table. I'm sure there must be a better way than trying to use rope!

COOL! It reminds me of the casinos in Las Vegas.

Nicely done, and beautiful artwork!

Nicely done! Very challenging game!

How is this different from mine, except that you moved the wheels to different positions?

I don't know why that happens on your computer. But you do not need to use the NEXT button. Simply drag the scene to the left, and you will see more pages.

I think you mean "water pump". Good job!

Oh, Okay. I didn't notice that!

Fun to watch! Good job!

I tried to make my own version of this experiment by placing a large container of water on a standard spring scale (not a balance), but I was not able to make it work. The problem is, no matter how much density you make a geometry (for example, 100Kg) and then you liquefy it, the resulting water has a density of only about 5Kg! Then when I slowly lowered a circle (fake sphere) into the water, the total weight changed only a very tiny amount. I personally do not like using a balance type scale for this experiment because it does not give a numerical value of the change in weight of the water when the sphere is lowered half-way into it (which is really what this experiment is supposed to show).

If you limit the torque of each motor to about 90 Nm, then the gears won't jump off the rack when they reach the top and bottom limits of travel. Just a friendly suggestion.

Your script in the spawned circle "onCollide" is:
e.other.density := e.other.color := [0.2, 0.2, 0.2, 0.0];
e.other.collideSet := 0

You need to change it to: e.other.density := 0
You do not need to change the color or the collideSet because the circle will be gone!

Hope this helps.

Funny scene (made me laugh!).

e.other.materialName == "fire" || e.other.materialName == "wood" ? {

Those two vertical bars are the "OR" logic symbol (the | symbol is the shifted function of the \ key on your keybord). So, in plain text, that script says, "If materialName is "fire", OR materialName is "woood", then do whatever you want to do.

Another handy logic symbol is && which is the "AND" logic operator.

I agree with 1 thru 4. But apparently, you do not yet have grandchildren.

Ahhh... I didn't see it that way, but now I get your point. I was taking the strict guidelines of the article as how the experiment MUST be done, but I see now that there are other ways of demonstrating the experiment, and this is one of them. Thanks for the detailed explanation!

Nice effect!

I guess my "rope machine" concept became popular for people to customize!

EDIT: The electric bill for lighting 2880 lights must be enormous!

I want to get a box of "Algo Crunch" cereal. I'll bet it tastes great!

When I rock my computer monitor, the bubble moves. Weird!

The clapper is hanging from the wrong spot. It should hang from the inside center at the top of the bell. Fix that and then it won't be so "nooby"!

Not too bad for a first scene! In time, your scenes will improve.

By the way, you can EDIT your scene so that other people do not have to make additions to it. Just fix the scene on your computer, then click on Edit on your scene here on Algobox, and upload the edited scene.

A nice improvement would be to label each material so that people know what material the different colors are.

Is the hammer supposed to move? If so, you didn't explain what key to use.

Nice idea!

One important function it needs is the ability to control when a droplet gets deposited onto the work table (rather than a continuous stream like you currently have). (Sorry, but it's my turn to nitpick! )

Works great for me. Excellent game!
