Let's Make Oobleck! 1  Mix 1 part water with 1.5 to 2 parts corn starch. You may wish to start with one cup of water and one and a half cups of corn starch, then work in more corn starch if you want a more 'solid' oobleck. 2  Mix in a few drops of food coloring if you want colored oobleck.
A cameo is a material that is carved with a raised relief which often depicts a profile of a face or a mythical scene. They are made most commonly out of shell, coral, stone, lava, or glass. The smaller carvings that are incorporated into jewelry are set in either gold or silver.
If you cannot see through the cameo at all, chances are the cameo is not shell. If you see any fine cracks or crazing while inspecting the back or front of the cameo up against the light, this is an indicator that your cameo is made of shell. Next look at your shell cameo under a 10x loupe from the front.
