Helium is so expensive these days... have to try this

4

no helium! just fill a water bottle 1/3 full with vinegar with a funnel. With another dry funnel, pour baking road into balloon (about 1/2 way). Cover top of bottle with balloon. DON'T LET BAKING SOADA SPILL INTO THE BOTTLE. Then lift balloon and let baking soda fall into vinegar. Mixture will fizz and expand balloon!
