Dear John Park,
It was awesome to actually meet you in person! I've seen a bunch of your videos for make TV. It's so cool the stuff you get to make! I haven't had a chance to make any of the things you've shown, but I can't wait until I can! I like the t-shirt cannon best so far. I also really really liked the little train typer thing you did. I wish i had one in my house, then i could send messages to my sister using a little train track.
