The shell of this water prism is made of cheap, clear plastic sheet normally
used to replace broken window glass.
Naturally, this giant prism will break up sunlight into beautiful, rich spectrums of color. I have one on the window sill where I am working right now, and I never get tired of pausing to contemplate the rainbow-like patches that move across the walls. But giant prisms can also create hilarious visual distortions of perception, as my son demonstrates at right. Walking while looking through a giant prism distorts your visual perception so much that your paces become an other-worldly adventure.
This project is one of the most challenging in this site. It involves using heat to bend plastic.The construction pages will walk you through step by step. Look them over. You can build this project for less than one tenth the cost of buying it from a science supply store.
