  There are many interesting science experiments out there for young kids. You can surprise your friends and teachers with them. All you have to do is to put a little effort into it and you should have no problem coming up with an in?teresting science experiment. One such experiment is to show your friends and teachers that you can make mothballs (棒腦丸) dance!If you want to do it,first,be sure that you have got all the necessary sci?ence kits for your science experiment.

  What you need for this experiment is a glass filled half full with water. Add a little bit of vinegar to your glass of water,about 1/3 or 1/4 of a cup (60 ml) ,and one teaspoon (10 ml) of baking soda,and then carefully stir the mix?ture. Drop a few mothballs into the glass and have your audience watch. As long as the surfaces of the mothballs become fairly rough,they should begin to bounce up and down in the glass.

  You can also do a similar experiment with raisins (葡萄干) and clear pop,such as Sprite. In this experiment,all you have to do is to fill a glass with Sprite and drop a few raisins into it. The raisins should begin to bounce up and down in the glass of Sprite. You can also replace the raisins with mothballs and you should get the same effect in the Sprite. This project works because the irregular surfaces of the mothballs and the raisins hold some C02 bubbles (氣泡) ，causing them to bounce up and down in a dancing motion.
