Ingredients
4 packets quick-set jelly (knox gelatin)
1 litre sparkling lemonade
1 packet Rowntree's Bursting Bugs (I'd guess gummy worms would work, Yankees)
You will also need a clear plastic bowl (25 cl) per guest

Instructions
Make up two of the jellies according to the packet instructions, using lemonade instead of water for stage two.
Fill the bowls 1/3 full, then leave until set.
Position two or three bugs in each bowl.
Make up the other two jellies, again using lemonade.
Allow to cool for a couple of minutes and then pour over the first layer and bugs.
Allow to cool for an hour, and then decorate with an additional bug on the top.
