I am going to build a balsa wood bridge. The rules indicate that I can only use 1/8″ x 1/8″ maximum balsa wood; Elmer’s white glue only; span 18″ w/ 1″ bearing at each end; width & height a max of 5″; entire bridge must be able to pass thru a square 5″ x 5″ aperture. Bar will be placed across mid-point to apply the test for structural effuciency. Any advice would be much appreciated. Shoud I use the glue straight w/o any water?, etc

If you’re using hot glue to make a bridge for science olympiad, then it’ll weigh too much. I learned that it’s really strong, so if you don’t care about weight- GO FOR IT!!!

I am building roughly a 50cm (length) x 19cm (height) bridge out of balsa wood. Would you recommend I use Gorilla Super Glue or Elmer’s Carpenter’s Wood Glue? The bridge needs to be as lightweight and be able to hold as much weight as possible.

although hot glue is good an all, it does not have very much rigidity. Because it is just plastic, it does not stick to the wood all that well. and when you put weight on it, the glue will slowly but surely deform and your whole brigde will sag until it finally collapses.

I see that hot glue from a gun is not mentioned. Why not? It seems to be strong enough and like CA sets immediately. Any down side?

Gorrilla glue is great stuff. It requires that you put water on the wood prior to applying the glue. It will foam and expand to 4X the volume of glue applied. It is very light weight. You will need to clamp the pieces together or they will be forced appart by the foam.

What about gorrila glue? I heard it’s the strongest Wood Glue on earth… Why doesnt wood glue work good on popsicle and other wood bridges?

Elmer’s carpenters wood glue works great for elevated bridge and The wright stuff!
