Maintain the Ideal Temperature of Your Drink With a DIY Insulated Plastic Cup
Whether you’re drinking at a party, barbecue, or in the office break room, this simple plastic cup insulation trick can keep your drink at the temperature you want for longer.
Obviously, you’d be better off with a thermally insulated cup or mug, but sometimes you don’t have one on hand and you have to get creative. This is where the idea for the InstaCool cup by Instructables EurekaFactory comes in . You take one plastic cup, a paper towel, and then a second plastic cup. Fold a hot dog-style paper towel (long paths) and wrap it over one of the cups. Then slide on the second cup as if you are going to stack them. Additional insulation slows down heat transfer; this means the liquid in your cup will stay cool or warm longer. You also don’t have to worry about condensation dripping all over the place. This is probably not a gimmick that you want to abuse as it can be wasteful, but it will help as a last resort.
