What could my aluminum foil ball be?

I’ve been carrying around an aluminum foil ball around in my pocket for that past week, and I’ve gotta say, it’s been a ball!

I will hold the ball with my hand in my pocket and imagine various scenarios:

• I imagine it’s a major league baseball that I was able to squish down with my bare hands.
• It’s a globe of a planet, and my hand is exploring all the various craters and mountains.
• It’s the moon. I was able to reach up and grab the moon and stick it in my pocket.
• It’s a deadly time bomb that I have to hold onto or else it will explode.
• I try to squish the ball into a denser and denser ball until it’s so small its density is like that of the sun where a teaspoon weighs like 12 tons or something ridiculous.
• It’s a pokemon ball with a really small pokemon inside. I imagine all the sorts of creatures that would possibly lurk inside.

If you were carrying around a small aluminum foil ball in your pocket, what would you imagine it to be?
