I also have green candy, so I will be making one to show you with those colors. and tomorrow I hope to make one with bath salts!
I looked high and low for the test tubes, too. Papertrey sells them, but I bought mine online at SKS Industries. I knew I would need a lot of them! SKS sells them for about $.41 each, but you have to buy 48. But using 5 at a time, I will use these up pretty quickly!
My daughter took one look at these and said....those tubes do not have enough candy in them! Good thing one gift has 5! Thanks for looking!
