 i am currently in 9th grade in an elective class where you can build and make anything that you want with the supplies and tools that they have and our teacher is really laid back when it comes to monitoring projects and making rules. one of our final projects was to make a belt buckle out of tin using a plastic mold we cut out using a [cnc router](http://www.multicam.com/images/router/1000classic.jpg). something i should point out now is that our teacher doesn't watch what were doing, he will show us once how to do something then leave us to fend for ourselves. so me and another senior student are dicking around with liquid tin and making mold castings without the teacher. i ended up successfully making around 5 or 6 castings and left them on the side of the table to cool. the castings were still really hot and could easily burn you if you aren't careful.some of the unsuccessful castings have bubbles underneath them so there is a hole in the middle of the belt buckle, if you melt the bottom of the casting then you can fill the hole back up but you have to be pretty precise. in my attempt to fill the hole back up i leaned on the table and my forearm landed on one of the hot castings burning my skin which resulted in me yelling "shit!" across the classroom. it didn't look bad at first, it looked like it only burned a couple layers of skin off and was a little red. everyone was looking to see what happened and the teacher looked at my arm and said that its just a second degree burn and that it will go away in a couple of days...he was wrong, in fact it got worse it looks like i have a brown nike symbol on my arm that slowly leaking puss and its probably not going away for a while. but on positive side, at the end of the class our teacher had a box hard drives that were donated from a company and he didn't need them so he gave me and my friend a 1 terabyte hdd and a 320gb ssd. turns out that the one terabyte hard drive was busted and got the clicking of death.
