This one works great when you are serving a crowd and don't want to be tied to the blender all night.

Make up 1 small can of lime-aid
I cup of oranje juice
1 can of 7-UP
1 5th of tequilla
Pour it all into a big bowl (tupperware's Thatsa Bowl works great) and put it into the freezer. You can do it the morning of your party or the night before.
Of course you can add more of less of anything to suit you taste, and doubling will also work.
I wish I could come to your party!!!!
