There's a certain satisfaction in fixing something complicated with only the simplest of parts, and your own ingenuity. Over the last few weeks my handheld milk frother looked like it was heading for an early death. The spinning motor still worked fine, but the groove in which the metal frothing wand sat was wearing away, leading to the tragic outcome of the spinny bit sinking into hot, bubbly milk every time.
Putting my brain and thumbs to work, I took a tiny piece of sticky-tape and wrapped it around the top of the wand. This increased the girth just enough for it to stay inserted during rapid spinning. Problem solved for practically nothing, with the most basic possible components.
I'm not going to worry over the semantics of how the roll of tape got into my office, or how sticky-tape was invented.
