I am making a toothpick bridge. The final mass of the bridge must not exceed 40 grams and it has to be at least be 30 cm long. There are 28 grams in one ounce. The mass can be less. It has to hold at least 1 kilogram (2.2 pounds) and extra credit will be given for more kilograms held which I definitely want.
What kind of bridge would be the best for holding the weight? How should I design it and go about it? What kind of glue should I use?
Thank You.

triangles will likely be good.
my guess would be something w/ few joints b/c the joints may tend to break.
also arcs are good. you know, like an upside down parabola/catenary.
A combination of these would be best if you can manage... I might even break the toothpicks to make things fit better if necessary.

A) If I blame the bridge and stomp on the materials than burn them I may/might be externalizing blame, however at the end of the day at least the bridge had existed and the materials may/might have been the cause of it's demise. B) I'd merely shrug my shoulders without blaming or worrying about responsibility and attempt to build another toothpick bridge if I desired to do so otherwise I'd put away the toothpicks and worry about bridge building another day.

Your basic unit should be the triangle, as this is rigid and won't buckle.
