Leonardo Da Vinci's 10 Best Ideas

Here is a link a list that was compiled of Leonardo Da Vinci's 10 Best Ideas. Some of them are pretty cool, actually all of them are.

9) Scuba Da Vinci’s fascination with the sea spurred many designs for aquatic exploration. His diving suit was made of leather, connected to a snorkel made of cane and a bell that floated at the surface. Proving the artist was also practical, the suit included a pouch the diver could urinate in.

5) The Aerial Screw Modern scientists agree it may never have lifted off the ground, but Da Vinci’s "helicopter" design is still one of his most famous. The curious contraption was meant to be operated by a four-man team and could have been inspired by a windmill toy popular in Leonardo’s time.

3) The Self Propelled Car It's no Ferrari, but Da Vinci’s designs for a self-propelled vehicle were revolutionary for his day. His wooden “car” moved by the interaction of springs with geared wheels. Scientists at one museum in Florence built a replica in 2004 and found it worked as Da Vinci intended.
