World's Lightest Ramps

[Munchskull]

So half way through the first day of our district event today, I went with one of our mentors to buy supplies for a ramp. The requirements we had for this ramp were simple, it had endure constant usage for two days minimum, it had to quickly move totes to a flat position, and finally it had to be quickly built with only a pits worth of tools. Here is the kicker it had to weigh in at less than 1.25lb.

I am happy to say that we successfully built such a ramp. Its final weight is 1.1lb and works fast. It is made out of packing tape and pink shop foam from "Home Depot". This ultra light ramp is saving our team and has helped us up our performance.

This exprince has lead me to wonder, what is the lightest ramp you have seen and what was it made of?
