This product and its effect I think gets passed more than it should. As someone who does many birthday parties for kids, I can attest that these are a great way to open for your magic show. I begin my magic shows by making balloon animals and when I transition from that to starting the actual magic show I usually begin by producing these. The kids love them and they are very colorful. For me, they are a great opener magic trick to your actual opener. For the price, portability, and simplicity of it, its a great way to get your shows started. I've had reactions from amazement to laughing, to somewhere in between. Don't sell these short.
