1 adult Warm half of the clay by working with it. If needed, flatten the clay into a round disk and heat it in the microwave on a wax paper covered plate for about four minutes. The outer edges will get hot first and may become gooey. Rub petroleum jelly on your hands. Push the palm side of your hand into the clay. Have a friend push your fingers into the clay (figure A). Try to get as much detail as possible. Form second half of clay into a disk and heat -- again about 4 minutes. Lay your hand back in the first palm mold. Have a friend push the second half of clay on the back of your hand. Push hard so you get detail. Try to work around your fingers where the two pieces of clay meet (figure B). You want to try and get them mashed together. Also, pinch the edges of the clay together to seal it -- you don't want plaster leaking out when you go to cast your hand. CAREFULLY wiggle your hand out of the mold. Make any repairs necessary. Lay a second plate upside down over your mold and tape the edges of the plates together (figure C). Mix plaster according to manufacturer instructions, usually two parts plaster to one part water. Be sure to get all the lumps out. Pour the plaster into the mold and let it cure for 1 hour. Remove the plaster from the mold and clean off the edges (figure D). Use the plastic knife to clean off seams and extra plaster between the fingers. Paint as you like and seal with shellac. If you use a spray shellac, make sure you spray it outside! Tips: - NEVER pour plaster of Paris down the drain or toilet. It will clog the plumbing. Always wash your hands and utensils outside.
- Have an adult supervise if you heat the clay in the microwave. Heat in only 2-minute increments to avoid getting the clay too hot and burning you.
- If any of the fingers break off -- have an adult super glue them back on.
