Well, as long as the invention was actually useful, and improved lots of people’s lives – then I’ll have to say that. Also, it depends on where I was going on the trip, and whether or not I was staying in some kind of amazing 5 star hotel!
It would depend on the invention. If it was a life-saving invention, then I’d go for that. If it was a stupid invention, like a solar-powered torch or a bannana straightener, then I’d probably go on the school trip.
