Writing on a balloon

I always keep a handful of balloons at home. They can be used in many ways to keep the child moving.

Here, I was writing over a balloon and also asked my child to do. She noticed the airy feel when you write on a balloon.

Also, she used a sketch pen to write whose ink does not stay on the balloon. It can be wiped off with hand. And sure enough, she messed herself with all the ink.
