Our everyday activities turn on the performance of nature's main engine: we may breathe harder going uphill, but we put more strain on our muscles walking downhill. Those of us who are right-handed can tighten screws and jar lids more forcibly than we can loosen them. Here we're treated to the story of how form and performance make these things happen--how nature does her work.
Steven Vogel is a leader in the great new field of bioengineering, which is rapidly explaining the beauty and efficiency of nature. His talents as both scientist and writer shine in this masterful narrative of biological ingenuity, as he relates the story--and science--of nature's greatest engine.

Enjoyable For Our Dogs
Color: 3 Colors
Very durable material. They have a little squish too them for easy pick up for our 50 pound dogs. Our dogs love all balls. They have a little weight to them, but not excessive for a medium to large size dog. We have an English Springer Spaniel and a Goldendoodle. Fun for playtime, but you probably won’t want to throw them around the house.

Awesome dog toy
Color: 3 Colors
Theses are great tough squeaky dog balls. Last a long time unless the dogs lose them outside,. Just the correct size for a german shepherd.

A little too hard for our dog.
Color: 4 Colors
These are definitely durable balls. They are a harder than our dog prefers. He does play with them a little and enjoys squeaking them, but he doesn't like to play fetch with them and that is primarily the only thing he really enjoys doing with balls.

Heavy chewer approved.
Style: Ball, Size: Medium (Pack of 1)
My pomsky will destroy a toy in minutes. Ropes, and the "indestructible" nylon type stuffs are no match for my furry shark. This ball has stood up to him like David. He loves the crunch and it is so much more tolerable than a squeaker. These will be a staple in his toy box - Chuckit toys are really the most durable dog toys I have found in three years.
