Duct tape? Check.

Perhaps the most useful item I have brought to Uganda is my roll of duct tape. Originally my plan with it was to take it to the Equator and place a little piece of duct tape there, so as to be able to say that I had patched up the Equator (still haven't done that).

Turns out I've had way more uses for it than I had imagined. My sunglasses broke the other day (Gucci...), easily fixed with a matchstick and some duct tape. The rim of my headlamp cracked; not a problem, just a bit of duct tape, and it was as good as new. Found out that the one chair they had on the deck of the ferry from Ssese islands was broken in several places. This took a bit of creative taping, but needless to say, duct tape saved the day.

It's like they say: if you can't fix it with duct tape, you haven't used enough.
