Smoke Ring Machine: Watch this video on YouTube: https://youtu.be/QB2e_kLAHOs. To create these smoke rings, I used an ultrasonic mist maker and a compact 6-watt pump. You'll need to fine-tune the spring so it's perfectly horizontal in the water. A small torch is ideal for this job, but you can also use a lighter if needed. Adding weight to the tumbler will give you the perfect punch. The hole is precisely M8-sized. Check out my other designs for even more innovative projects! The outlet of the pump measures 13mm in diameter.
