Submarings Handheld Water Game | Retro Mini Ocean Ring Toss STEM Toys for Adults, Girls & Boys Ages 6-12

This is a great toy for people who remember the old Parker Brothers Cartesian diver (PBCD) from the early 1970's. This version is almost the same size but is designed without the black metal band.The bottle was a little deformed probably due to storage pressure differential but it popped back out. The lid is plastic which is better than the PBCD.It is admittedly fiddly and somewhat temperamental to set up. The key is to get rid of the free bubbles in the bottle. The diver itself needs to contain a bubble of air INSIDE the for this system to work. I set up the toy by dunking the whole bottle into a large bucket of water (AND BELOW the water level of the bucket) and shaking out the free bubbles which "sticks" to the rocks and plastic accessories. This also ensures you do NOT have a gap of unfilled space in the bottle once the lid is screwed into place (screw the lid under the water level of the bucket).Again- Patience is needed to set this up.The toy works when the bubble of air INSIDE the diver is compressed and causes the diver to sink. Extraneous bubbles outside the Diver is one of the reasons why this toy will not work.Anyway this is a great walk down memory lane without spending a lot of money buying a collector's original from the 1970's.I almost forgot to add: Over time the diver will naturally stop working because the bubble inside the diver diffuses - this is normal. The toy will have to be refilled and reset.Don't let it sit too long filled with water. It will get moldy.

I liked that the product came with educational information and instructions. It's a great value, durable, and a smaller size toy that makes an awesome gift.

Amazon glitch states for a few weeks my product is late but I received it previous to the late notice, so Luki Lab was actually quick to process my order. The toy is great for adult and kids, lol...notice adult first. Love the physics aspect of it. It's also built with quality, making the price fair. I'll be checking out what else they offer! Recommend this company. 😁

Fun but leaks no matter what we do.

I had one of these when I was a kid and thought about it often, And I was excited to find it on Amazon and still made basically the same , A fun little toy to have around!

Like some reviews stated, the buttons are too hard to push for it to actually be an enjoyable game (even for an adult). Will be returning 👎🏻

Neat Cartesian toy from my youth. They solved the rust issues from the original nicely. The reason I can’t give it 5 stars is two reasons: I think the blow mold bottle is too thin because it make a loud pop upon squeezing which affects the grip of the divine toy and the base plate will not stay attached when in use. They did offer to replace or refund but it wasn’t worth the trouble and shipping for a $20 toy.

Fun for the whole family! The adults and kids all enjoyed trying to get the little diver to pick up the tiny treasures. It was fun to assemble, really fun to play, and has an educational aspect. A fantastic alternative to the traditional board game. The instructions describe three single player games, and three different games that can be played with two players. Highly recommended, and makes a fantastically unique gift!
