You can have a fun pumpkin smashing event at your house (or just with your family.) You can experiment and see what methods can smash a pumpkin the best.
For example:
- Stomp with your feet
 - Throw against a wall
 - Drop the pumpkin from a certain height
 - Hit with a bat
 
Once pumpkin is smashed, you could use the leftover pieces for composting. You could also use the stem, or pumpkin chunks to paint.
