Recently, Avi and Akshna got some balloons. And recently having learned that if they rub them on the hair, they get some static charge and can be stuck to walls, they got all the balloons to stick to one of the walls.
I asked Akshna to do an experiment. Since one of the balloons had just enough helium left to float mid way in the air, I asked her to cut some of the thread and see what happens. When I got back home last evening, she said she had done it. I asked her what happened, and she said it went up a little bit. I asked her why would that balloon go up. And she correctly theorized that it’s because the balloon got a little lighter.
I told her she was a scientist now, and she laughed and got all silly.
