My friend and I were making Harry Potter wands for the release of 'The Cursed Child' this month. We used dowel rods, and we covered them with hot glue and beads before painting them to look like tree branches.
We used acrylic paints, and I got a big red cup with water for our paintbrushes. Halfway through telling a joke, I got thirsty and instinctually reached for the cup of water. I took a big ol' swig of dirty paint water.
The best part was that my friend was so polite that she said she was going to pretend that she hadn't noticed.
