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
