Music hides inside everything from rulers to jelly jars, and you can make it come out if you know how to whack, thwack, twang, bang, pluck, pucker & blow the notes from their hiding places. During the week we'll build & learn to play dozens of ad hoc musical instruments, put together a rousing ensemble video performance, and upload it to YouTube. We'll also learn about the physics of sound and explore the basics of music theory such as pitch, rhythm, timbre, and harmony. No musical experience required, just a consent form to appear in the video.

Your home may be your castle, but only if you can hold it against all comers. And since the best defense is a good offense, maybe the place to start is preemptively swiping theirs. If this sort of logic appeals to you (or if you just like the idea of turning sticks and ropes into machines that bash, toss and fling) you need to attend the Siege Engine Workshop. We'll construct working scale models of various ancient castle neutralization devices plus a pair of castle walls, learning some carpentry, history, ballistics, and physics along the way. Then it's war!
