Are there any actual straw cups that don't leak milk?

I'm in southern California right now where we're going through a big heat wave. So the milk is constantly rising up our of the straw because of temperature. And it's getting everywhere. It's obviously making my wife quite annoyed because of the mess. So I'm looking for an alternative to the munchkins weighted straw cups. I bought 2. My son literally threw one and it cracked. And they both just leak endlessly.

I don't care how much I have to pay. I just need an excellent alternative
