That white one didn't wanna pop huh?! I got too sexy while filming for YouTube. I am sure my naughty looner friends here don't mind seeing this side of me! I blew up these balloons on a live stream and they have been sitting for a week.So they were not full and tight anymore. I try to sit to pop and squeeze a balloon with my legs to try to pop it. It seems I just have to dig my nails in until it pops!
