Create a magnetic pinball game and a labyrinth of Legos My son and I have experimented all morning with our Legos. With much trial and error, we made a Lego labyrinth. We used our Lego base plate and we put bricks on it to create complicated mazes.
cardboard tubes + box = hours of fun! We pieced together TP and paper towel tubes. Used marbles. The kiddo loved it and even still pulls it out to roll the marbles into a dump truck. He wont' let me toss any cardboard tubes now.
The bolts are graded in diameter for a more difficult exercise. Five slotted bolts and stubby screwdriver. Designed by a Montessori teacher to aid the development of eye-hand coordination and teach a practical skill.
