How do you make plasma?
We worked on evenings and weekends during the month of October with help from several makery members and in the end we made a pretty good hammer.
Well, usually air insulates electric charges, so it requires high voltage to break apart the molecules.For a variety of reasons, Patrick and I took it upon ourselves today to build a new aluminum-melting furnace based on some old refractory (insulating) firebricks we had in the shed. .The relevant episode (S1E2) can be found here:.We dubbed this bludgeoning device The UnMaker, and used to unmake things that needed unmade.As part of OMGs outing to Kansas City Maker Faire this year, our own Eric Kaplan was interviewed for a PBS show called Wicked Awesome Stuff.The biggest time-suck was recutting all the bricks to make a 6-sided structure (the original kiln was 8-sided, so the angles needed changed). .Id watched a few videos on and sort of dove. .We also need to finish up the lid and finish tidying up a bit, but Im super happy with how it turned out for 3 or 4 hours of work.Ben helped out with the handle design (using a taper and a retaining pin) to make it replaceable in the future, and Eric put a coat of orange paint on the finished product.If you have any questions about online word puzzle maker registration on our site, how to apply for a particular grant, or anything else we can help you with, please contact our customer support hotline at (Toll-free.S.In a partial vacuum, however, this breakdown potential may decrease enough that two uninsulated surfaces with different potentials might induce the electrical breakdown of the surrounding gas.
