This is similar to our Glitter Fireworks. In fact, many kids said it looked like fireworks. However, it's more abstract and you don't get huge globs of glue that take days to dry because the kids aren't squeezing from a bottle. The glue actually slows the marble down and you have more control than when using paint. (If it's too slow, you can add some water to the glue.) And the finished product is so sparkly!
