An entertaining game, and a physics lesson rolled into one.

Justdrag the cursor over the “trap height” slider to release the hot atoms.
My highest BEC count was 25.
Using **Frank’**s trick I got a 19. Yea.
34 seconds, first try, no cheats, right side.
You may kiss my ring.
Same, but I got 32 seconds the first try. 
(But I’m sure that’s just because I got a good starting randomization.)
Muahaha 26 seconds on my first try. Without reading any of the posts here.
I got bored and stopped at 158.
Oddly enough, after a few tries, mine was all 50. I hit the restart button and the atoms collapsed before I could touch the trap. A fluke.
