How to Make a Kaleidoscope

Lay out the two microscope slides flat and paint the top side of them black. Set aside to dry. Note: Always be careful handling glass.

Start with the cylindrical beverage bottle. Cut the screw top off the beverage bottle neck with the saw or knife. Discard the top. Carefully and evenly, cut the bottom off the bottle on its maximum diameter at the lower edge of the label wrapping. Take the contoured body bottle and cut the bottom off also at the lower edge of the label wrapping. This contoured bottle bottom should just fit inside the other bottle. See Photo Above
