One of the highlights of summer in Japan is attending local natsu-matsuri, or summer festivals. While many in attendance don a summer yukata as they take in delicious festival food and drink, enjoy performances and music, the bigger summer festivals in Japan are headlined by spectacular fireworks shows.

This summer has not been an ideal one for outside gatherings, but that doesn't mean the colorful bursts in the night sky are gone. Traditional Japanese tableware maker Shun Japan is taking the show to your dinner table, releasing a set of sake drinking glasses that give off a transformative fireworks display as you fill them with a cold drink!

The sake glass set, decorated with a festive fireworks show, put you in a summer mood on their own, but quickly evolve into something even more vibrant when filled with a cold beverage.

The sake glasses are coated with a special paint that reacts to temperature, so a drink is poured at 17 degrees Celsius or lower (62.6 degrees Fahrenheit), the color of the fireworks change, true to the shifting but beautiful display witnesses at a summer festival in Japan.

Here's a video showing off how they work.
