It is discovered by my 1M students!!!

Clever!

Here are the steps done by them:

1. Add 2 drops of perfume () into two balloons (NOT inflated yet)

2. Inflat both balloons and tight them.

3. Smell from the surfaces of balloons.They've found that both have good smell from the surfaces. (of coz you may

know why!!)

BUT, a 1M student stated that:

The larger one (pink) has a stronger pleasant smell () than the smaller one

(red)!!
