In my dream I was running water for a shower, waiting for it to get hot, when I noticed the water wasn’t draining from the tub. Kneeling down to get a closer look, I could see sand piled up in the drain, so I stuck my little finger in and scooped some out. I kept tweaking it out a little bit at a time with my little finger until I realized that was going to take forever, so I went to the kitchen to get a clear plastic drinking cup with a lid and a straw. I put a hose over the end of the straw, punched a hole in the top of the lid, and by sucking air through the hole I made a little vacuum cleaner that I could use to suck the sand out of the drain. It’s weird how even my dreams can turn into nerdy gadget projects.
