Just thought I'd post a few of Jer's latest creations:

Aircraft Carrier. This was 2 stacked canning jar boxes with a flap on the upper "deck" which lowers as Jer's model fighter jet lands. It acts as an elevator to the lower, inner deck!

Hot Air Balloon. This was a mylar balloon from his cousin Haylie. He tied the ribbon to a yogurt-cup "basket". The basket had a cut-out door and a plastic "Mrs. Mattinson" (his principal, who actually rode in a hot air balloon at their school!) hanging out of it!
(sorry, no pinwheel picture)Pinwheel Pencils. Jer found a pattern for a pinwheel in his "365 TV-Free Activities" book. He figured out he could pin the center to a crayon or a pencil eraser and it would spin! He was kind enough to make one for each of us in the family.

Golden Gate Bridge. He connected two apple boxes (hooray for Costco!), gift wrapping ribbon, and push pins to create this life-like model! He even made up a story to go with it.

Locking Box. This involved a shoe box, the box's lid, a plastic roll from some now-gone gift wrapping ribbon, a shishkabob stick, and the remainder of the now-gone gift wrapping ribbon. The mechanics of this are pretty cool--as you turn the reel, the lid lifts on the hinge! (If you turn it to close it, the lid actually locks shut!)
