Not really sure if this is classed as a craft but here goes anyway.
I have no room in my kitchen for a Slush Puppie machine, I have way too much baking stuff so I don't even have somewhere to store it when not in use either. I do love a slushy on a hot day so I needed an alternative. Slush Puppy brought out pre filled pouches that you could just buy, put in your freezer, smash it up a bit and there you have a slushy. With these they are very limited to the flavours you can get. I liked the idea so I wanted to try and make my own the same way using reusable drinks pouches. It worked so that's how I made my slushies at home.
