These crystal glasses by Luna & Curious look like normal wine glasses, but they are not. Fill the glass to the line marked D, and the glass will play a D. Drink a bit, and it’ll play an E. They can be played by running a finger around the rim, or by tapping the side. Oh the fun that could be had with these. And I most certainly would break one every single time I play one. Yup.
