Mix contents of each container thoroughly. One gallon zip-lock bags work well for mixing. Make sure they are sealed tightly before mixing! Pour container 2 into Container 1. Gentlylift and turn mixture until all but 1 tablespoon of liquid is left. Flubber will be sticky for a moment or two. Let excess liquid drip off and Flubber will be ready. Store in an airtight container when not in use. Will keep for about 3 weeks. Yield: Enough for 6 people.
