I've probably got the name wrong. Usually found this at Mott's five-and-dime. Kit came with a small tube that you could squeeze, then you took a small straw and wound the goop that came out onto the straw. Then blow into the straw and the goop inflated and hardened into a multicolored balloon. The stuff stank to high heaven.
