Flying Tea Bags!
Tea Rockets Explanation
First, we place a tea bag tube standing up on tin foil. The foil won't burn because of the aluminum inside. When we light the tea bag on fire the flames burn down because the fire is looking for the easiest molecule (Fuel) to burn.
The air in the top of the teabag gets hotter, making the air less dense. The tea bag is almost fully engulfed in flames. The fire reaches near the bottom. Suddenly there is enough cold air and hot air to create a vacuum, flinging the tea bag into the air above.
Well done!
ReplyDeleteI love the short sentences you use to make things clear and readable. The diagrams are also clear and concise. Well done!
Maybe you could have included a look at why the hot air makes it float? A discussion around density would have helped me understand some more of the science behind the action.
