Runaway Pumpkin

Our last Tinker Time STREAM challenge was lots of fun. The boys continued their ramp building skills, but now also needed to think of a way to STOP the pumpkin safely without damaging the pumpkin.

Lots of ideas for building the ramps was happening, but the pumpkin kept falling off the ramp. 

So, before designing and building the STOP, they had to create a fence to keep the pumpkin ON the ramp so it would make it to the very end.

Here we go...

YAY!!

Success!!

THIS was the sturdiest STOP!

Great job, engineers!
