Former NASA and Apple engineer. Current UKupr and friend of science. \n\nAnswers to some common questions:\n\n1) I studied Mechanical Engineering in School. I did my undergrad at BYU and Masters at USC.\n2) I worked for NASA JPL for 9 years, 7 of which were working on the Curiosity Rover (I made a video about it you should def totes watch cause it's probably my favorite of all my videos). Then I created Digital Dudz (made some videos about this too) and eventually sold it after 2 years. Then I worked for Apple in their Special Projects Group doing Product Design as a Mechanical Engineer for 5 years. As of 2019, I just make my monthly UKup videos.\n3) Link to free and therefore substandard build plans for my custom workbench can be found below.\n4) I made a 30 Day Creative Engineering Class that teaches my end to end engineering process so you can make stuff too! Check it out here-\n

    Rather than just a spray I'd use 4 chambers and 4 co2 cartridges to fully spray and siphon the skunk spray at once and in short delays from each other. Complexity is an issue here but much more coverage and less likely to be covered by the case again as it will be hard to stop a dump rather than a squirt.
