A few weeks ago, I went to Maker Faire here in Austin. Maker Faire is a fair primarily sponsored by MAKE magazine, and built around the idea of making things yourself. Needless to say, there was a lot of cool stuff:
Mad science blocks - These things kind of speak for themselves, actually. Because really, do you know any kids that are getting enough mad science in their lives?
The Diet Coke and Mentos guys - Now imagine this video, but live. It was really neat to see, even though there was enough of a crowd to prevent me from seeing very much. Afterward, they handed out the (mostly empty) bottles of Diet Coke - apparently it tasted minty for some reason. >_>
Robot battles - Do you remember those TV shows they used to have, where the robots would go into an arena and try to destroy each other? (If not, you seriously missed out.) After taking that robotics class last year, I feel like I could probably design a way better robot than the ones we saw; maybe I should try it sometime.
Musical Tesla coils - The video explains it better than I could, actually. This was by far one of the coolest things I saw that weekend.
CNC Lasers - Seriously, who doesn't enjoy watching things getting cut with lasers.
Rattlesnake skeleton bike - Yes, it's an actual bike; no, I didn't get a chance to ride it. Just watching it was pretty impressive in itself, though.
That's all for now; there was more cool stuff, but if I don't start studying for the tests I have tomorrow then I will literally die. :(
