Both were filled with air on the same day, but the red one was on the floor and the pink One was in da closet anyone explain?

Pink one in the corner... Probably just had a better knot tied

Here are a few reasons that might have contributed this:

1. Temperatures in the closet might have been warmer compared to the floor
2. Since it was a handmade knot, the balloons cannot be equally tightened.
3. Not all Balloon are properly sealed from the manufacturer, defects are expected.
4. Puncture took place after
5. The balloons were of different size
