Want a cool homemade treat? You can use dry ice as a mould for the perfect juice popsicle.
Grant Thompson "The King of Random" demonstrates this on his YouTube channel. Get a block of dry ice and carve a popsicle-shaped groove in it. Make sure there is somewhere for the stick to rest and then pour in whatever juice you like. After it freezes, pull out the popsicle, and be sure to dip it in some warm water before trying to eat it. The popsicle will be extremely cold and if you try to give it a lick before dipping and warming the outside, you'll have a tongue-stuck-to-the-frozen-pole situation.
