Glow Stick

Glow sticks are chemistry-related items, which can be lit up in the player's hand for a limited time.

Crafting
Light Gray Dye creates a glitched Glow Stick called item.glow_stick.silver.name.

Usage
While equipped, glow sticks can be used to shake them, causing them to appear bright regardless of the light level. This is only an aesthetic change, as no light is emitted to the surrounding area. The glowstick's durability depletes while lit.

Trivia

 * Putting two glow sticks in a grindstone results in getting a glitched item called item.glow_stick.black.name
