National STEM Day - November 8, 2025 - Engineering Challenge

4:00 AM


Looking for something fun and challenging to do on   National STEM Day on November 8, 2025?  Why not try this challenge?

All you need is 20 toothpicks and 25 marshmallows for each team!  The large marshmallows work best for this challenge, but you could also use the small ones!


We practice for about 10 minutes, then we spend 25 minutes building the marshmallow towers.  The towers need to be free-standing, they cannot lean on anything!

Materials can be found at your local dollar store or grocery store!  I plan on grabbing 3 bags of marshmallows and two boxes of toothpicks for my own classroom!

This is the perfect day to get engineering!
