Make sure you follow our homemade toys board on Pinterest for more ideas, and don’t for get to pin the Pin at the bottom.

The credit for this activity goes all to YC; we were talking about how we were going to make our own Ker-plunk and I was thinking of using a bottle, but YC came up with a most ingenious idea; a Lego version of Ker-Plunk! What a great idea was that! Much better than my bottle idea.

YC was thrilled when we built it and we spent an afternoon having a Ker-Plunk tournament with YC, EC, a friend and myself.

You will need:

  • Lego bricks
  • Bamboo skewers
  • Marbles

When you make your tower make sure that you leave lots of holes for the skewers to go through. We found it easier if you made holes opposite each other otherwise it is really tricky to get them through into another hole. You also need to leave a gap at the bottom for the marbles to roll out through.

When all the skewers are in place fill the top with marbles.

To play the game:

Each person takes it in turn to pull out the skewers. If any marbles fall down to the bottom on your go then they become yours.

The person with the least amount of marbles wins the game.


I loved watching YC and her friend play together, they kept pulling the skewers out from the bottom and would say with glee “I didn’t get any marbles”, of course their strategy came un stuck when they then had to pull the ones out from the top and ALL the marbles came tumbling down.
