Building a kaleidoscope is a great project to do with your kids or friends, and it teaches them about light refraction. After making your cut glass triangle, you'll be ready to cut a kaleidoscope tube. This is the tube you'll look into when you use your kaleidoscope.
Instructions
1. Gather the materials for your kaleidoscope tube. You'll need your cut glass triangle and a mail tube, cardboard tube or PVC pipe.
2. Hold your cut glass triangle up to the tubing and place a mark a couple of inches longer than the triangle.
3. Turn the tube and mark each of the other sides a couple of inches longer than the triangle. If you'd like, you can connect the marks to form a cut guideline on your kaleidoscope tube.
4. Cut through the tube with an utility knife or saw. Depending on the type of tube you use, you may need heavy equipment to cut it, or just a pair of scissors.
5. Sand the edge of your kaleidoscope tube with a fine grit sandpaper to remove any jagged edges.
