Caterpillar, Catepillar where were you hiding? - DIY

I had a bunch of these colorful plastic balls which my sons had outgrown. I tried giving those off to my neighbours, but they each had a set already. These light weight plastic balls are so universal, you see. :) Anyways, I found a boy in the neighbourhood who could play with these and gave a few to him. But few more had successfully been hiding for a while before I collected those and just put in a closet, thinking someday I will use those.

Car parking DIY activity for boys

 We constructed a two level parking with cereal box and empty tissue rolls.  Cut out one side of the cereal box and use it as the base. Glue four tissue rolls cut in halves for the pillars, on four sides. Glue  the other part of the cereal box over the tissue rolls, as shown in the pictures. Then we marked the parking spaces with yellow masking tape.
