“What will you take to the moon?”
If I were going to the moon I’d take as many of these spiky things as they’d let me take. My brother and I used to have so much fun throwing these at each other in the living room I can’t imagine they wouldn’t be twice as fun in zero-gravity.
They’re perfect for bringing in a spacecraft because they’re really squishy and basically can’t break anything. You can throw them with little risk of harming important space equipment. Plus they’d look hilarious floating around.
