Today we each made a serving of ice cream. Put the following ingredients in a sandwhich size ziplock bag: 2 tablespoon sugar 1 teaspoon vanilla extract 1 cup half and half (For flavored add chocolate syrup, candy pieces, etc.) Make sure after it is sealed you squish it around so it mixes together.
Fill a gallon size zip lock bag half full of ice and add a handful of rock salt.
Put the small bag into the large bag, seal, and shake, shake, shake. Believe it or not, in about 5-8 minutes you get ice cream! Less equals milkshake. Be careful: Make sure you rinse the ice cream bag with ice water before you open it ...otherwise salt residue will ruin the taste.
I was great fun on a hot day!
Science project: This will take a week, but it is oddly facinating. Submerge an egg in vinegar for a few days and see what happens! (The shell becomes soft...like a peeled hard boiled egg...try to squeeze the egg into a bottle without breaking the egg...let the shell reharden...kids will be amazed at how you got an egg into a bottle.) If you need any other crafty projects let me know.
