The most efficient bridge is at 3:41, with an efficiency of 1010, carrying 20,280 grams. The design seems to be a fairly straightforward truss, with members going straight down with diagonal members going from the top middle to the bottom sides, with a longer member going almost all the way towards the middle, going diagonally to the sides of the bridge. The bridge fails on the right far side, near the support, and it looks like the glue joint failed and/or the wood sheared off from the glue.

Whoa... Safety glasses are between $9 and $17USD.
Childrens' eyes are priceless. Z.87+, available thru local hardware stores.
good point :)
how about some safety glasses in the future. Other than that a nice project.
Agreed, next time :)
