Repair a destroyed car



Pretty impressive rebuild of a unibody car - stretched back into shape with chains and panels replaced. 
This can hardly be worthwhile unless you have wholesale prices for the parts you replace. I guess pricing is probably quite different in China.

How trees work






4:29 Why do trees only use 5% of the water they transport? To survive:

"To make sugars, plants must absorb CO2 from the atmosphere through small pores in their leaves called stomata. However, when stomata open, water is lost to the atmosphere at a prolific rate relative to the small amount of CO2 absorbed; across plant species an average of 400 water molecules are lost for each CO2 molecule gained. The balance between transpiration and photosynthesis forms an essential compromise in the existence of plants; stomata must remain open to build sugars but risk dehydration in the process."
