Holding a homemade piezo mic in a bowl of soda pop and pouring in Pop Rocks candy worked perfectly. For the sound of breaking ice, try using a large piece of polystyrene. Give a twist so it slightly squeaks then make it snap. Then use the sound of a small metal money box dropping sharply on the ground and mix it with the other.

While it's unlikely that you're going to see a LEGO Coca-Cola Machine at a mall near you anytime soon, YouTuber ElectryDragonite has taken the task upon themselves to create a fully functioning vending machine out of the tiny building blocks. Not only does this LEGO Coca-Cola Machine offer four beverage options, but also features a coin return system that will provide change.
An internal cooling system within the LEGO Coca-Cola Machine allows drinks to be dispensed at a cold temperature, while the system itself is powered by two Mindstorms NXT controllers. While this LEGO Coca-Cola Machine might only hold a handful of beverages, it's a clearly awesome achievement by ElectryDragonite and might just become a common DIY for those who want an at-home vending machine.
