Question: What would be the easiest thing you have built in your life as an engineer

Hmmm, I dont know off the top of my head. I’ve built plenty of little kits (from Maplin) that do cool stuff, but nothing stands out.

I suppose one pretty easy thing would be this – Get some copper wire, wind it around a nail or a bolt, and put both ends touching a battery. You have now made an electromagnet! Amaze your friends with its paper-clip picking up abilities!!!
