Gelatin Pool

The Gelatin Pool is a scam that Eddy came up with in "Knock Knock Who's Ed?" The scam was exactly what it proposed to be: a pool made out of gelatin. To create, the Eds built a wooden crate in the middle of the cul-de-sac, attached a diving board to it, and filled the crate with water. Edd and Eddy then carried a giant bag of instant gelatin to the crate and dumped it in.

As soon as the gelatin solidified, the walls of the crate collapsed, revealing a gelatin pool in the middle of it. Eddy was gleeful about the possibilities that the pool represented, and to test it, Ed dived in. When he was in the middle of the pool, however, immersed and stuck in the gelatin, he sucked it all into his mouth, wrecking the scam and making Edd feel ill.
