Knuck-Crackers Conversation Starters

  1. Can you crack your knuckles? Ask your family members too. Based on this information, do you think being able to crack your knuckles might be a genetic trait, as in, passed down by family members?
  2. Set up your own thumb war competition! Name your competitors (your thumbs) just like Gramma G-Force did! Come up with your own special winning move.
  3. We learned that there is no scientific connection between knuckle cracking and arthritis. Talk with a family member about what other “bad” habits might not actually be bad for you? For instance: do you think if you make a silly face it could actually “get stuck like that?”
