Building a Bridge out of some odd duck items?

Question

I am building a bridge for my class and need some help in the design of the bridge. Here is a list of the items I get:
1.) 100 toothpicks
2.) 200 feet of string
3.) 25 feet of aluminum foil
4.) 10 paper clips
5.) 10 rubber bands
6.) 1 Roll of Scotch Tape
7.) Pair of scissors
8.) 12" ruler
9.) hole punch
10.) 10 pieces of construction paper
11.) 10 note cards

The bridge has to span 5 feet and hold approximately 100 pounds on top of the bridge. I only get 30 minutes to build this bridge in class also. I will have 7 people helping me.

Also, what is the best design in case the weight is hanging from the bottom instead?

Please help.
