I doubt that this video needs a lot of explanation…
When I made the WD40 and hammer machine my instagram exploded with people who liked the automatic WD40 sprayer. In this video I do a bit of research (yeah, lets call it research) on what works and I make four different automatic spraying mechanisms.
I first improve the first WD40 sprayer that I made by using pneumatics, this made it a lot more reliable. I also show my process for designing a sprayer mechanism like this and try if it works with silly string.
