4th of July Cool Science Experiment – Colored Smoke Rings

I’ll have to admit that my Trash Can Smoke Rings routine is not only a signature staple in my stage show, but it’s become one of my all-time favorite science demos to perform. After presenting my smoke ring routine on the Ellen Show, I received a flood of e-mails with questions about the smoke machine and where to purchase the device. Unfortunately, the cost of a good smoke machine can be a deal breaker for many smoke ring enthusiasts. That’s why I’m hoping you try my latest variation… Smoke Bomb Smoke Rings.

    I think that video is so cool, just like the other ones! I would love to do it on 4th of July but I’m going to be on my vacation.

    Loved the video and made two vortex generators myself today. I was amazing the neighborhood kids and I plan on taking it to my buddy’s 4th of July party. My only problem is I can’t tell if I’m tapping them too hard or if my bungee cords aren’t tight enough because I have to constantly tighten the membrane. Never messaged on here but maybe I’ll get a response. Any thoughts?

    I’d try two bungee cords to keep the membrane tight. I just found a new style of “flat” bungee cords at Home Depot and they work great for keeping the membrane tight up against the side of the trash can.

    This would be something that I would love to try. I’m sure my grandsons would love this as much as they love the bubbles we have so much fun with. I’ll have to do this sometime when my 12 year old nephew is around to assist me with it.

    I’m working with a student on this project. We were wondering if you could clarify how bernouli’s principle drives the demonstration.

    Do you have a “how it works” section posted somewhere.
