I want my balloon to be extra full for my Birthday!
I don't think this will be a good idea. That balloon looks very full.
Let's go inside now.
POP!!
Hi! I'm Gracie the dog. You are probably wondering why this happened. Well, this is simply Charles' Law
You blew the balloon so full outside when it was cold. According to Charles' Law when the Temperature Increases the volume does as well. This is why the balloon popped since it was already full and you brought it in to a warmer setting making the volume get bigger and the balloon not be able to hold that much volume.
