Algodoo

By AeroMatic

These toys are fun to play with in water!
Guide:

Red, twisty thing is fun
Orange, Loosened gear
Yellow, Normal Marble
Green, 10 N Attraction marble
Purple, -10 N Attraction marble.

To use, just pause and move the toy into
the water area.
You can also extend the area
a little bit to make it more fun.

Thanks,
AeroMatic
