Folding Trailers > 8 Yr old response to a simple problem. ( in case the link does not work)
The kids and I were starting to pack the PU for a 8 day trip and I was attempting to find out how much space I had above the mattresses. I had put a roll of paper towels in to see if it would get smashed. After explaining to him what I was doing he just looked at me with a funny expression on his face, then he disappears into the house. A few minutes later he returns with 3 woopy cushions. At least that is what we refer to them as, you blow air into them and when weight is applied they release the air sounding like some is passing gas. He fills them with air and proceeds to put them where I wanted to check the space available. When I lowered the roof you could instantly hear when the space was to small for the cushion. The kids thought it was great and would hoot and holler when they went off.
TOOO FUNNY!!! And what a smart kid you have!
Great idea! Leave it to an 8 year old to come up with such a GREAT solution to an "age-old" problem!!
What a brilliant child!!! LOL This is too funny!
