cutting and bending glass and putting toothpick in balloon

This week we did two experitmentsl, bending glass and putting toothpick in ballon.

We wore goggles for our safety and cut the glass before we burn the glass.

We used nail file to cut the glass. After we made damage in the glass, we broke the glass whcih faced downward. Then we put glass above the fire and made glass melt and bend slowly. We had to be careful because it might burn your fingers. It was interesting experiment.

We blew the balloon and tied the top. And then we picked the sharp toothpick and put vaseline on the balloon and toothpick. We were scared to put the toothpick in the top of the balloon so we asked someone else to do it for us but he also failed. I regreted after him by not trying. I could success instead of him. Anyways, I knew tht balloon could hold sharp thing on the top of the balloon.
