Welcome to another post on my blog. Today, in Chemistry, we had done a 'Teabag Rocket Experiment' using a teabag. We first learnt about convection, it's meaning and how it moves around.Convection

As heated particles expand and move faster they also rise up. As particles get cooler, particles sink because they are denser (particles get more closer). The process continues eventually the whole liquid would get heated up. The movement is called Convection Currents. This can also be seen in the air.
Aim: To observe convection in real life
Equipment:
- Heatproof Mat
- Teabag
- Scissors
- Lighter/Matchsticks
Method:
- Get a heatproof mat and place it on a table.
- Using scissors, cut the top part of the teabag and tip the tea out in the rubbish bin.
- Make the heatproof mat into a rectangle standing up.
- Using a lighter or matchsticks light the top part of the teabag.
- Observe the teabag fly up on the ceiling.
Observations:
When the teabag is lit it gets enough energy that it goes up till the ceiling. When it reaches the ceiling, it becomes less dense and becomes lighter. When the teabag goes down, it slowly goes down and turns into small particles if touched.
