my friend Shawnelle. She came up with the coolest party theme- Mad Science Experiments! Seriously what nine year old boy wouldn’t want to blow up mentos and diet coke at his birthday party. She commissioned this lab flask to go with the carbonated ice cream they were going to make. It was hollowed out on top so that a cup with dry ice could make the cake “smoke”. Hopefully, I can get a picture of it in action later, but for now, here is the non-smoking version.
My son kept asking me if he could go to the party.
BUTTERCREAM 
How fun! I wanna see it work too!
