Jell-O [TM] Jiggler Eggs
Since mention of Jell-O Eggs received a wildly enthusiastic response from the Outer Boroughs board, here's the info for making them at home.
Some chowhounds remembered making Jell-O eggs by blowing out eggshells, sealing the bottom and pouring the Jell-O in. Kraft sells a plastic mold ("etched" inside with spring-y decorations)that lets you make six eggs at a time.
If you want to amaze your friends and neighbors with (e.g., blue) Jell-O eggs, you can call 1-800-435-0917 and order a mold for about $3.25. Or you can check out the link below. The millenium mold also looks intriguing.
I neither work for nor own Kraft stock. Just want to improve the quality of life for other tacky food aficionados.
