that's it, jpb. i couldn't remember the name. we used sassafras to make the syrup for the soda.
taxy, you need a quart and a gallon ziplock bag, milk, sugar, vanilla extract, ice, and salt.
you pour some milk, sugar, and vanilla in the quart bag and seal it. then put the sealed quart bag inside the gallon bag, fill the gallon bag with ice, pour in some salt, seal the gallon bag, and then get busy mushing it all around. as the salt melts the ice, it freezes the milk and sugar in the inside bag. by mushing it around, you break down the ice crystals in the milk as they form, thus making ice cream. it only takes a few minutes and it's a lot of fun to do with kids.
I was given a soccer ball type ice cream maker. Same principal but you play with the ball instead.
