I was also disappointed when I checked how many true IMAX theaters the movie is playing in in the US. We have a real IMAX theater in our natural history museum in my city, but Oppenheimer won't be playing there :(

I had a friend as a kid who had ducks as and I can answer this. They poop. Everywhere. A lot. Also they're loud as hell sometimes.

Life hack: all you really need is a lighter and your favorite flavor of hairspray or spray paint.
