Magic Cap / Cap

Want a bottle of icy drink in hot?
Be splashed by the bubbles when opening the cap?
DON’T WORRY. Our team designed a MAGIC CAP. And here is how the cap works.
There are two parts of the cap, the upper one and the under one. The first thing you need to do is to pull the upper part up when you open the drink and there will be a crevice on the top. So the bubbles will fly away through it. Then the liquid level will become lower and there’s no bubble left, you can rotate the under part of the cap to open the bottle. With bubbles go away, you will never be splashed. Finally, enjoy the fantastic soda water!
