tea bag fun

 In Room 10 we were trying to make tea bags fly but Mr Raj was getting the wrong tea bags. Not once, not twice but 5 times 6 times lucky (hopefully).  

The next day I brought some more tea bags which were different. Some of them were flying low and one went right up to the roof.

I was happy when I saw my friends excited.

In my mind I saw fireworks exploding and raining ashes to the ground. Here is some science behind this experience.  

As the flame burns it heats the air inside the hollow center of the tea bag. As the air gets hotter the air molecules become less dense and move around. The less dense warmer air rises above the more dense cooler air around the tea bag. Since the tea bag is so light it rises with it so it  flies.

It felt so awesome to be part of the experience and having fun with my friends.
