Newton's Cradle

Pepole r stupid 2 say its stupid coz it does egsacly wat it says on the tin :)

Gets realy boring after you do every thing with it in two minutes

Graphics suck and if you turn it upside down, it doesn't recognize the change in direction. I want it to tangle when upside down.

Very clunky and the physics is all screwy.

Nice realistic stimulation. And Kinnolo, yes the real ones do stop. After about two minutes. It's not a perpetual motion machine.

Cool, but volume should be proportional to hit force. Allow balls to be lifted. Increase touch sensitivity, ball weight and friction.

Sounds do not work on motorola devour. Slow simulation not fast and sharp like the real thing boring background and housing.

Just like the other eric said gets boring after a while

Try to pull up a ball in the middle while other are in motion. Yeah! Time machine.

Boring and useless. We just learned about them and it does not even work right

The balls need to move a little faster. Feels fairly real otherwise. And the strings don't get tangled!

gets boring. when I close the app it would still sound but stops after awhile.

For some odd reason, the motion starts decaying, which defies Newton's Laws

Accelerometer just makes it go in circles. Once it starts, you can't restart it. Lame.

Works fine.. its just completely useless!

It is ok, though it gets very boring, and it has bad graphics and no 3D.

No sound besides that not bad kind of useless though- Droid 2

Turned on the accelerometer, accidentally hit the phone and the balls got tangled up.

Gets realy boring after you do every thing with it in two minutes

lol @ perpetual motion machine... got bored after 1o seconds and uninstalled!

Nice idea, but slow and boring. No metal against metal sound. 2.5/5 stars.

Its soooooooo fun my daughter plays on it for hours she hogs my phone! We have competions to see who makes the most introresting thing

A good concept. A bit glitchy. Seems like a bad ripoff of the iphone version

The sound is annoyingly unrealistic. Very poor use of the accelerometer, far too sensitive. And very poor graphics.

Stupid app. Way better on the iphone.

It is really calm....it calms you down

Doesn't have much features and poor graphics. Still nice, though.

Quite fun, but sometimes the balls overlap. Uninstalled because I need more memory. Desire.

I kid you not, i was lf this just the other day and found it today by accident. Works ok. Good start, but sound needs work.

but… but… I want one in real life :'(

Used to be great, but the last update ruined it, and weeks later still no fix. Shame.

Collisions are a little too static, and the balls sometimes stick together after a collision when the shouldn't.

Fun little app. Would be cool if all marbles would interact with each other rather than just the ones to either side of them (a.k.a ball 1 and ball 3)

People saying it gets boring after a while, do they not know what a newtons cradle is!

Prty fun, i love there things....balls all go up to top left wen i use accelarometer tho.....

The dev needs to study some elementary physics before making further progress...

Doesnt work, Evo 4G

Helps kill the boredom in the office.

Pretty good physics. Maybe have more designs and colours in next update. HTC Desire

The developers has been either lazy, or scarily unrealistic. The physics are rubbish and the marbles stick together when they clearly shouldn't.
