A U.K. ice cream maker has turned everyone’s favorite nighttime party accessory into an edible dessert.

Lick Me Delicious owner Charlie Harry Francis enlisted a Chinese scientist to churn out glow-in-the-dark ice cream, made from synthesizing the luminescent protein in jellyfish. Yes, jellyfish. The protein reacts with your tongue at a neutral pH and as the temperature of the mouth heats up, the raised pH levels trigger the glow, the inventor told U.K. newspaper Metro.

Francis released the illuminated dessert just in time for Halloween, but we doubt many bit into its price tag of almost $225 a scoop.”It is incredible stuff but still at very early days in terms of production,” Francis said. It’s unclear what the glow-in-the-dark flavor tastes like–or if it’s even safe. “Is it safe to eat?” The owner wrote on the site. “Well I tried some and I don’t seem to be glowing anywhere, so we’ll go with a yes for now.”

The boutique ice cream company also offers a non-jellyfish alternative, using quinine from tonic water, a popular way to transform food into nighttime-friendly fare.  Lick Me Delicious is known to cook up outrageous flavors like chili, lamb and bee. We think we’ll stick with mint chocolate chip.
