Tearing things apart and sewing them back together again.
Lol! I wonder if your students will go to class tonite in costumes....
There are usually a few. Many of my students come to class straight from work (heroic!) so their options are limited.
I would have loved to have been in class with a few costumed individuals for a change :)
It would be fun to dress up in something scary for lectures I think. Really, it doesn't take much by way of accessories to transform one magically into fancy dress!
