A Bridge Made With No Screws or Nails

In this instructible I made a bridge with no screws or nails and helps stop pollution and promotes recycled.

the materials in order to make the bridge include:

1. a heat gun
2. tin cans
3. plastic bottles
4. wood

the first step would be to frame out the size and shape of the bridge. in order to do this you would use the cardboard or wood and make a frame to later build upon. making the frame is important because it is the base its built upon. make a square frame with the wood then cut 2-liter bottles and position them at the corners of the frame. the 2-liter bottles can be heated from the heat gun and tightens to the form of the wood creating a airtight seal. in the picture you can see I highlighted where you should put the bottles.

using wood for the fence posts easily creates stability but of course you have to use the 2-liter method again to make it join together. next you make the stairs to your liking but yet again you use the 2-liter method. In the picture I highlighted where you could put the bottles.

the bridge is for pedestrian use only and is supposed to be used on trails to prolong bridge life by using plastic since its decay life is so much longer then natural materials. I wanted to make the plastic that pollutes our ocean into something helpful so that we can help stop pollution.
