Last week I did a project that was pretty simple, but interesting. Here is what it  is. First you get a glass cup that you can see through. Then, you cut out cardboard the same size as the diameter of the glass you’re using. Then, in that  cardboard circle, you cut a slit from the outside to the middle. Next, you take a paper clip and un-wind it until you only have one loop left in the paper clip.  Then you cut two tear drop shaped pieces from tin foil. Then you sick the end of the tear drop pieces on the end of the paper clip. Then you put the other end of the paper clip in the slit in the card board. Next, stick the paper clip dangling from the card board in the glass and tape the cardboard circle to the edge of the cup. Finally, blow up a ballon, rub it on some fabric and hold it next to the paper clip sticking up from the glass….. The tinfoil sheets will spread apart! I thought it was really cool and fun experiment!
