Professor Puzzle, the company that produces Newton's Gravity, has many clever designs in which a creative mind is needed to solve the problems they propose. Most of these can't really be called puzzles, as they usually require a simple trick or other clever movements to be solved. Nevertheless, like any other traditional puzzle, this one will make you think...

This puzzle couldn't be simpler. Two small wooden pieces, a cup and a bullet, work together to create a basic physics principle. However, you don't need to be a physicist to discover the solution to Newton's puzzle, but a resourceful mind will help. The puzzle is quite small and fits in the palm of your hand, measuring about 4.5cm (about 1.8") in diameter.

Newton's Gravity's goal, like its presentation, is as simple as it gets: you have to put the bullet inside the cup and then find a way to remove the bullet without moving the cup. This looks like an impossible task, since at first, your only idea to accomplish this is to tilt the cup upside down, but that's exactly what you're not supposed to do. How is this done then?

Ok, I must confess, this puzzle had me baffled for a while and I couldn't resist looking up its solution. I just couldn't figure out how to remove the bullet without moving the cup. It seemed to defy logic and rational thinking. I suspected there should be a trick involved, as some kind of illusion. Well, as it turns out, the solution is indeed some sort of trick, and knowing now how it's done, I reckon it would be a while before I could come up with such a creative solution. It's not an obvious or intuitive solution, that much I can tell you.

Without revealing much of the solution, I can say that the puzzle doesn't need to be exclusively on a flat surface. You can be holding it in your hands while performing the solution. Also, the solution involves some sort of propulsion, but that's about as much information I can give you without completely revealing the solution. It is very clever and simple, but can be quite difficult to discover it. I have to disagree with the 2/5 difficulty rating, though. I believe this is much more difficult than the designers made it out to be, even for experienced puzzlers. You won't find too many people out there that will be able to solve this in a timely manner. This is a level 4/5 at least, in my opinion.

Closing Comments:

Newton's Gravity is a perfect puzzle for a party, with lots of friends and family. Challenging people and observing how they try to solve it is probably more entertaining than many other collective activities.

Availability: You can find the Newton's Gravity at Brilliant Puzzles for just $5.99 USD.

"without moving the cup"... when I was looking and reading about this puzzle before, I thought it was without touching it. But movement changes the game. :) I'll try to think logically of a solution first, before even buying one to tease my relatives and friends with. :)
