Saturday. I played with crystal orange GL500 on my bed. It was new, inflated for the first time and felt very tight. Quite close to the limit...but could be even closer. And I couldn't get rid of this idea. So I unclipped the balloon and started to blow. One breath, two, three... how many more could it accommodate? I expected to count that but got way too excited and just kept on blowing till the final burst. Well now I know how tight this balloon should be right before the limit!
