To make an instant cold pack, mix water and ammonium nitrate crystals. Start by filling a plastic bag halfway with water. Then, add ammonium nitrate crystals to the bag. When you're ready to activate the cold pack, squeeze the bag to mix the contents thoroughly. The reaction between water and ammonium nitrate absorbs heat, resulting in a cooling effect. Always seal the bag tightly to prevent leaks, and for added safety, you may double-bag it. Use with caution and follow safety guidelines when handling chemicals.
