I could not imagine really like and whether the work Eiskugelformen me.
My conclusion: it works flawlessly. It fills the form in the closed position over 4 small holes with tap water. I think after that the holes at the same time with my fingers in order abzuschütten excess water out of the mold. Then I make the shapes horizontally in the freezer.
ATTENTION:
For an oblique bearing these forms are not suitable, because then at the side of the water would leak out of the Eiskugelform. Do not stack more can not be the forms even if you have, for example, two of them.
After the freezing process you pull off the lid and the silicone is really flexible yet dimensionally stable. The scoops come out beautiful. If you put water filled to the brim, then there are balls with a small tip and our men round enjoys liked the fact that it then looks a little like a bosom.
Especially fine are these ice balls when similar a mint leaf or a raspberry before the lid on Insert puts in every sphere.
In the item description is given BPA-free, on the product itself, unfortunately I could not find any indications. I rely now just that the message in the description of the manufacturer is correct.
