Step 1: How It's Done
This science experiment is very simple and it does not require any special practice. Materials used are readily available in houses. Here we need a needle, candle and two glasses for support. You can use anything for the support. First cut the candle from both the sides so that it can be lit on both sides. Now pierce the needle in between the candle and balance it using those glasses as shown above than light the candle from both the sides and it's done. After this just watch the fun and see how the candle starts reacting. It happens because the center of gravity of candle changes all the the time and to balance the candle moves up and down and it goes and goes.
Try this science experiment at home and amuse your kids with it.
