Hey, sorry it's taken me so long to respond. A year in fact... sorry! And I don't really know. Two of those beach balls I blew up in my videos on my old YouTube account I got from school and they were used, so I'm guessing other people had likely blown them up before me. And I'm 16 now.
Hi puffy cheeks. Another person here who likes to blow up inflatables by mouth too as well as big balloons and sharing blowing things up with others. If you want to chat about all that sort of thing and more, then please drop me a line. Cheers. Steve.
