The piece is sculpted with Plasticine and cast from fiberglass resin. These are not the best mateials to use but they are cheap and get the job done.
I was inspired by Sylvia's Super Awesome Show, she made it look easy.
Step 1: What you need
Plasticine (oil clay)is used for making the master shape. Real Plasticine is meant to melt hen it gets to about 100C which would make it easy to get out of the mold. Unfortunately mine was a knock off that just caught fire.
Plaster of Paris is for making the mold. you pour it around the Plasticine sculpture.
Not pictured is Lego, for making a box, and plastic wrap or aluminium foil for lining the box.
