Bridge and Junk

Our (My) Bridge weighed about 11.5 grams which was able to hold 115 batteries which was about a 230:1 ratio.

This is my bridge across a 12 inch gap

This is my bridge slanting from the weight of the batteries

This is the bridge about to break from the weight of the batteries



After the repairs and redesign, the bridge weighed about 12.6 grams, and was able to hold 267 batteries which was a 490:1 ratio, meaning our bridge was the winner!

I don't have a picture of the redesign, but i added 2 toothpicks on both sides where the strings would be. 1 horizontally, and 1 vertically. These 4 toothpicks, and some reinforcements on the joints made it possible to hold 152 more batteries!

If i were to redesign it again, i would reinforce the joints on the end of the bridge to keep it from sagging on the end.
