Ultra High Velocity Shop-Vac Nozzle

thingiverse

This nozzle attaches directly to the shop-vac case (no hose needed). The air from the nozzle is traveling at incredibly high speed: Enough to make very large skin waves. Please use ear plugs to prevent the large pressure differences from hurting your ears. The pressures are many, many times larger and just being next to it made me want ear plugs. Be safe! This is intended for fun, high speed aerodynamics experiments. I am currently working on a supersonic version of this nozzle, but the plausibility of such a device is to be determined. Notice the lip for adding you own attachments. Instructions Print and smooth the interior the best you can. I used heat, then a coating of Elmer's glue for a sleek finish. Next remove the hose and put the nozzle on the air out port. Next buy ear plugs for the people that will be within 10ft of the device. Now turn on the shop vac and have fun! Be mindful of the temperature of the motor because the nozzle adds resistance (I suggest a one minute on, one minute off duty cycle).
