what if we try this?

i typically let the kids try stuff without telling them how it will
end. lessons are always more permanent when observed directly. and
hey, they may end up inventing something that will make us all easily
and disgustingly rich.
right now the kids are experimenting with sledding down the stairs in
laundry baskets, sleeping bags, on top of pieces of cardboard, and etc
into a pile of pillows.
the neighbor kid says "have you ever tried doing this in the office
chair?"
i will have to step in and intervene on this one.
