Peyton and I went to Lakeview Museum to see the Knex display. We walked around and watched each of the different carnival themed displays. At the end of the exhibit, there is an area where you can build with the Knex blocks/bricks. The kids can play and if you would like to purchase their creation, you are charged by the ounce. Peyton wanted to make a helicopter. I helped him build it. We used one pound of Knex. Cost me $12.
