Guys... I cannot express that a huge smashing success this presentation was. It knocked my socks off..
The kids had so many questions... Three really kinda shocked me... (paraphrasing..)
#1: When you send Bitcoins around the world, do they go up through a satellite and back down the other side?
I stumbled on this one for a little bit because I wasn't prepared to teach 4th graders about asymmetric eliptical curve cryptogaphy and message hashing. LOL.. They put me on the spot, so I dont recall exactly how I answered. Something about the Bitcoins dont really "go" anywhere, you're just using cryptographic keys to sign off amounts everyone knows you have. Sigh.
#2: What happens if you don't want a Bitcoin address anymore? Can you just delete it?
Wow. Um, well you can forget it exists and never use it again... I somehow got into the example of being able to create thousands of keys at a time and delete those and a little about how it relates to being anonymous.
#3: Can you make Bitcoin addresses anything you want (besides those long ugly strings)?
I told them about VanityGen and being able to specify a string of text you want in your keys when you create them.
There were so many more really awesome questions, but it's all a blur now.
But the bottom line, I think I've found a new passtime and audience. The teacher was equally impressed and I'm positive this will get around to the rest of the faculty and I'll be invited back to do it with other classes from 4th through 12th.
Getting bombarded with all these questions from little skulls full of mush was an outrageously exciting experience. MOAARRR!!
