In March 2010, the residents of La Cañada Flintridge, Calif., cooked up a community center fundraiser that netted $5,000 and a television episode on TLC. With 5,000 pounds of snap, crackle and pop, 7,000 pounds of marshmallows, and help from food scientist Todd Menaker and mechanical engineer Scott Stukel, community volunteers mixed up the world's largest Rice Krispies Treat.
Volunteers worked for two days in an outdoor kitchen that Stukel designed on the community center's baseball fields. They avoided a sticky mess by dumping butter and marshmallows into 2,000 vacuum-sealed bags, and then melting it in huge vats of just-under-boiling water. The goo was smooshed together inside the bags before getting oozed into boxloads of cereal and mixed with paddles. These "small" batches were hauled up platform stairs and piled into an enormous mold.
At final weigh-in, the 12-foot high, free-standing Rice Krispies Treat logged 10,470 pounds.
