This was a dessert I served last year for Halloween and I'm already getting requests for more! I stippled black StazOn on the test tubes and filled them with Pop Rocks after they dried.
This was a HUGE hit and truly easy to make! The tubes are plastic and I'm even able to reuse them this year!
If you'd like to see an in-depth tutorial I think the one on my blog is pretty easy to follow. It also shows the best part ... sprinkling the Pop Rocks on ice cream! Your kids (and even husbands) will LOVE this!
