A comprehensive survey of eighteenth-century knowledge about all aspects of light, Opticks also offers countless scientific insights by its distinguished author. One of the most readable of all the great classics of physical science, this volume will impress readers with its surprisingly modern perspectives.
In language that lay readers can easily follow, Sir Isaac Newton describes his famous experiments with spectroscopy and colors, lenses, and the reflection and diffraction of light. Book I contains his fundamental experiments with the spectrum, Book II deals with the ring phenomena, and Book III covers diffraction. The work concludes with "Queries" -- speculations concerning light and gravitation. Opticks is introduced with a Foreword by Albert Einstein.

Not Tuff
Color: Black Yellow Phrog, Color: Black Yellow Phrog
Absolutely terrible and not “tuff” at all. My chocolate lab had this thing destroyed in less than two hours. I would not recommend these for the price.

Cute but Not Durable
Color: 2PK Green Leaping Phrog
⭐️⭐️⭐️⭐️ Cute but Not Durable
Super cute toy—my dogs loved it right away! Unfortunately, they chewed the head off within a few hours. I ordered a second one because they were so into it, but the same thing happened again.
I won’t be ordering a third, but they still play with their two headless frogs. So while it’s not the most durable, it definitely kept them entertained!

BUY IT!
Style: Baguette
This is AMAZING! My golden retriever loves it with hidden snacks on it or not.
I wouldve put some more snack stacking on it, but dotn hesitate, BUY IT, its undestructible and fun.

Cute but not durable at all
Style: Crepe
Cute toy but not a very durable toy for my Doxie. Was ripped apart in less than 30 minutes. She had fun though.
