Shave the balloon

Shave the balloon is a coordination game. You can play it with any number of participants.

Equipment

 * balloons
 * disposable razors
 * shaving foam

Procedure
The balloons are inflated, then shaving foam is put on them like if they were heads (you can also draw a face on them if you like). Then, using the disposable razors, the participants have to "shave" their balloon clean again. Who can do that without hurting (destroying) the balloon?
