This is really a tip for anyone involved in the technical side of theatre/music etc. (an industry that both of my parents know well) but you never know when it might come in useful.
So, you're having to clear away some cables that have been stuck to the floor with gaffer tape. Take a moment, and think. It may seem like a short cut to pull cable and tape up together, but do so at your peril. The two sides of the tape will stick together, and you'll spend hours (probably) trying to get the tape off.
Never say the things my mother taught me aren't varied...
(On cable related topics, I was once taught by a BBC technician how to properly wind electrical cables. Knowing how to do this, he assured me, would allow me to impress and therefore ingratiate myself with any technical staff I had to work with. And it's never a bad thing to have the tech crew on side. I was a sceptic, probably like you - how important can cables be? But he was right; on at least two separate occasions I have revealed this knowledge to techies who have been so impressed I even know that there is a specific technique that they invited me to join the crew.
So what is the secret? Well, I'm not going to tell you, it's far to valuable...)
