Just had this conversation with Miss 8:
Miss 8: "Why did dad buy Mountain Dew?"
Me: "We want to make glow sticks with it."
Miss 8: "Okay"
She wasn't even surprised that we were planning to do some science experiements with Mountain Dew!
But yes, apparently, Mountain Dew, bicarb soda and peroxide creates glow sticks. We're going to give it a go a bit later on and see how much of each we need. Stay tuned.
[UPDATE]Apparently it doesn't work :( I should have checked out Snopes first! Oh well, it was fun to try[/UPDATE]
