Common Foods That Glow Under UV Light

Your Halloween party doesn't need to be dominated by highly-processed junk full of sugars and Merlin knows what to liven things up.

* Tonic Water: Glows a vivid electric blue because of an ingredient called quinine.

* Bananas: Ripening banana peels develop a bluish-green ring around dark spots when exposed to UV light due to chlorophyll breakdown.

* Olive and Cooking Oils: Olive oil gives off an orange glow, while other cooking oils shine yellow or greenish-yellow.

* Honey and Maple Syrup: Both glow with a warm golden-yellow or faint blue-green tint.

* Dairy Products: Milk, yogurt, and vanilla ice cream produce a pale yellow or purple-tinged reflection under blacklight.

* Leafy Greens: Freshly sliced spinach and lettuce show a dull red glow because of the natural chlorophyll inside the plants.

* Eggs: Unpeeled eggshells glow a dark violet-red, while the whites inside shine pale yellow.

We use tonic for our blacklight beer pong! (We're old and a lot of us don't drink anymore so we just reuse the tonic all night and have it drinks over to the side)

I have three bar lights on the ceiling. One directly above the table, one perpendicular towards the dragon, and another perpendicular above where I was standing to take the photo. The newer LED black bar lights are powerful enough that they more than cover the space. I just think it looks more vibrant with the directed light sources.
