The document describes how to make a "super starch" liquid that behaves differently than normal liquids when punched or pushed. It lists the ingredients as cornstarch, measuring cup, spoon, bowl and water. The instructions say to mix cornstarch and a small amount of water into a thick paste, knead it, then punch or slowly push fingers into it. Unlike water, this starch mixture will not make a mess when hit due to how the water molecules are forced between cornstarch grains, causing it to temporarily solidify upon impact.
