Well. I have one, too - my secret superpower is... being able to tie off balloons really, really quickly. The reason for this is my home town's annual fair, where my parents, among other volunteers, have been selling helium-inflated balloons for a good cause for 35 years now. When I was a child, I started helping out a bit, and when my schedule allows, I still go back there to help tying off balloons.
From being a small fundraising thing, this balloon sale has grown over the years, and letting hundreds and hundreds of them fly off at the official end of the fair has become a much beloved tradition. It is a stunning sight to see more than one thousand balloons go up and off with the wind at once, balloons in all kinds of colours (though there are quite a lot of red and blue ones, that being the town's colours). There's an added bit of satisfaction and happiness in it for me, knowing that I've had a hand, literally, in getting hundreds of these balloons ready. (I've calculated that I have knotted at least 700, probably more like around one thousand balloons on that one day. That, at the end of the day, meant very tired fingers, a bit of skin lost even though I've liberally, and very early, used tape to protect the skin, and a blister in one of the weirdest spots I've yet had one, right on the tip of one thumb. And the pleasant feeling of having done a good job.)
And for you, here's a little video of ascending balloons - by far not all of them are visible, as I didn't manage to get to the best spot for filming... but you'll get the idea.
