Plastic bottle....water bottle.
Pour Oil in first we used about 2 cups, then pour water we used about 1 cup.....you want more oil than water. Then food coloring, maybe 3-4 drops.....Jake went alittle color happy. Then cut or brake Alka Seltzer in to 4-5 pieces and drop in and watch the lava rise. Jake thought this was too cool.
