DIY Vacuum Experiment

*Parental supervision required*


Hello my science geniuses! Let's learn how to create a vacuum today! This easy experiment can be done in your home with the supervision of a parent.


Didi you know?

A vacuum is a space with nothing in it- not even air. Even sound cannot move in a vacuum!




What you'll need:


  • Candle/Tealight

  • Clear glass

  • Light surface like a yoga block

  • Matches

  • Parent :)


Step 1


  • Light the candle with the help of you mom or dad.

  • Place the candle on a light surface like a yoga block.



Step 2 & 3


  • Place a clear glass over the candle.

  • Press the glass down until the candle stops burning.

  • Now wait for about 2-3 minutes.


Your vacuum is ready!


  • Now try picking up the glass.

  • You will see that the light surface and the candle will also be lifted up along with the glass due to the vacuum you created inside the glass.


Explanation


  • When you light the candle, the flame inside the glass heats up the air in the glass.

  • This expands the air inside the glass.

  • As soon as all the oxygen in the glass is used up, the candle stops burning.

  • This cools down the air inside the glass which in turn shrinks it.

  • The expanding and contracting of the air is what creates the vacuum.

  • The vacuum then allows you to pick up the light surface along with the glass!


WE LOVE SCIENCE!
