I love it when my kids invent some cool stuff - like yesterday when they wanted to create a marble run on their own.
Some cutting and some duct tapping later we had our first homemade marble run!
PS: all work (inventing, cutting, ducttaping and beta-testing) was done by my two sons (age 5 & 7!)
Step 1: Creativity - Duct Tape - Cutting
The big fun is to be creative. Invent new stuff or try it: just cut some cardboard, bend it and ducttape it. Then give it a test run and build the next thing.
... and this is just the beginning. The boys are already thinking about seesaws, canon-like features and other cool things.
What you need:
- a knive and a scissor
- a marble for the test-runs
