You could of had the semi cellphone my mom gave me (through it into my closet and it was destroyed by the combined forces of my RC tank and a basket of my stuff.) Yesterday we only got to test on bridge and it was crazy when it broke it held 137.5lbs. The leader so far has held 200lbs. My friend Peter has alos used the same bridge as in the photo for his design. Mine it different from the orginal for the sake of creativity, but his is more like a smaller replica of it and I think his will hold 300lbs. I shooting for about 200lbs. - Peter

Well I tested my bridge yesterday and it held 145lbs, which is adequete for me. My bridge never really broke and splintered, every place where the glue was came apart, so if Iglue more I could of got 20 more pounds. Well the winner was my friend with 428lbs with the same exact design as the bridge I posted earlier, guess I picked a good design. I will try to take picture today of the destruction of my bridge, I couldn't yesterday since I couldn't figure out my mom's phone. - Peter

Well, congratulations and, I suppose, felicitations.  Too bad about the glue; I never put much stock in glue.  Nails are good, but screws are better. 

You might want to find out from your friend what type of glue he used and who manufactured it.  Could be handy in the future.
