Algodoo

The first leg of the elimination stage of AMR S1, and I did something about water.
50 will be racing, and 43 will pass.
How to use my starting device:
Move the marbles to the small boxes and there should be 1 marble per box. Next, edit the TimeToLive of the box just aboce the magenta portal in each starting box to what you want.
Other starting machines can be used, but be sure to downscale it.
