I wanted to tweak my last post on Reactions by getting a bigger and badder hydrogen gas explosion. I also wanted to get enough hydrogen gas in the balloon to make it float. The solution…higher concentration of an acid and put the zinc in the balloon and have it attached so the first big burst of hydrogen gas gets caught in the balloon.
If you’re not a chemistry mac-daddy like myself, just be patient through the first 90 seconds and nod your head with an introspective look so you seem like you’re really smart and you totally understand. Then enjoy.
