Today I spent the first hour trying to make some sort of ark welder while trying to find the least resistant metal as a welding tip. I found copper made the cleanest  weld because it has a very low resistance but something like steel or iron had alot of resistance making a bigger spark. I also found graphite lights up but doesnt take all of the power out of the supply shorting it. After i was done with this experiment I worked on my color sorter with Ivan and then switched to helping Mateo to try to get his UV remote working but then i ran out of time and did my job and typed this up.
