My point is, for about the cost of an easy solution (that, frankly is a lot harder to undo if done wrong) you could equip them to do it right, practice the skill you want to inspire and not plant the false idea that soldering is some difficult thing that the beginner should avoid.

You can get conductive adhesives but it would probably be cheaper to just include a soldering iron in the kit… I’m not sure I would be confident in getting good contact with self adhesive metal tape, your best option there is to probably get a small amount and experiment.

I think hammer and chisel was the common way.
