Here's a Summer Science Magic experiment to try yourself!
You will need
- A shoe box
- White copy paper
- Scissors
- Tape
- Sand-box sand
- A small magnet
- A paper clip
- The picture at right
Sand is made up of small pieces of rocks and minerals, including tiny pieces of iron called iron-filings. These small pieces of iron or iron-ore can be moved around with a magnet, to look like a Sand-Bug!
To make your Sand-Bug Theatre, cut the bottom out of a shoe box, and tape a piece of regular copy paper over the hole. Decorate your "Theatre" any way you'd like. (You can use the image above on the front!)
Bend open a large paper-clip so that it looks like an "L". Tape a small button magnet onto the paper clip.
To operate, spread sand over the top of the theatre, and move your magnet around underneath. Your "sand-bugs" should dance and race around the surface!
Got an idea of your own?
