Amazing Balancing Can

20130623-134922.jpg

This science trick is so simple, but so much fun. It’s also easy for students to replicate at home.

Equipment:
-Two empty 375ml cans
-Approx 100ml of water

Method:
-Secretly pour about 100mls of water into one can.
-Have a student try to balance the other empty can tilted on its bottom rim. It is impossible.
-Then amaze them, by easily balancing your ‘magic’ can on its bottom rim (they don’t need to know it has water in it).

Explanation:
It works because the water adds weight to the bottom of the can, changing its centre of gravity and allowing it to balance in otherwise impossible ways.
