For this Halloween, I needed a simple, low cost, but impressive costume. Maybe something science related (ungrad mechanical engineer at TCNJ currently)... Beaker from the Muppet Show seemed to be the obvious answer. The head is made of 1" thick green foam sheet from Jo-Ann Fabrics. The felt is attached with spray adhesive. Foam spheres are used for the eyes and nose with felt stretched over them and pinned in place. The felt was stretched by running it under warm water and pulling it. The labcoat was bought online and the tie from Thinkgeek. I can see through the mouth, and I strengthened the partially open mouth with cardboard. I see through a few layers of red mesh also picked up from Jo-Ann Fabrics. Jo-Ann also supplied the orange hair.
