smoke ring machine here you can see the video on youtube https://youtu.be/QB2e_kLAHOs i used a ultrasonic mist maker and a small 6 watt pump you have to tweak the spring to get it horizontal in the water, i used a small torch for it, but you can also use a lighter. you have to add weight to the tumbler to get a good punch, the hole is size m8 watch my other designs for more cool stuff the size of the pump outlet is 13mm
