I think about lots of things when i take a shower.. I asked people, how many balloons does it take to make a human fly? But then i realised that i am surrounded by modern tech, i could just google it.. So i did, it takes up to 5000 to 6000 balloons to lift a human. That is of course, the balloon must be filled with helium.
I also googled why lizards poo has a white tip at the end of it. so the white tip is a form of urea. And lizard has only one hole to excrete wastage. Cool eh?
