You'll have to place your finger over the hole so it doesn't leak and make sure they stay level in the freezer. When ice crystals form, they become less dense than water, so it freezes from the top down forcing the gas to come out of solution. Placing the hole on the bottom with water to retain the seal lets the air escape. Close the cooler for slower freezing, which takes about 2-3 days depending on your temperature. See the before and after pics. You don't have to spend all the crazy money on clear ice makers.
I bought 2 sets of 2, and have tried both hot distilled water and room temperature distilled water without success. Hot water results were 2 salvaged ice spheres, both cloudy with a lot of cracks (and 2 that fell apart). Room temperature results were 3 salvaged cubes (and 1that split in 2), also cloudy and and show lots of cracks. I’ve ordered a small cooler with the hope that placing the filled molds inside it will slow the freezing process and help get more clear cubes. I’ve had relatively good success with yield from other brands (both squares and rounds of various sizes), but still not getting “clear” cubes and spheres. In fairness, the molds are well made but I expected far better results.
Update: After some trial and error, my spheres are getting better so an update is warranted. There ARE some tricks. Distilled water! It does turn out that using these inside an insulated lunch bag helps slow down the freezing process and resulting in more clear spheres. Also, rinsing them prior to putting them into a cocktail will remove the frostiness and make them look like oversized glass marbles. Still not perfectly clear, but better. Don’t waste time boiling distilled water. That method (without using the insulated lunch bag) resulted in very cracked spheres that broke into pieces in a beverage. If they included an option to add &/or explanation for use of the insulated container, I’d consider an upgrade to 5 stars. 4 of these sphere molds, plus an insulated container to freeze them in, is still about 35% the cost of the Wintersmiths sphere mold with container.
Tip: You can get significantly clearer spheres of ice when You use boiled tap water before freezing. I love feedback so please let me know if this review was Helpful or not helpful.
