Letting kids chew or cut glow sticks is a bad idea.

While safer than sparklers and fireworks, pliable glow-in-the-dark products are easily broken open when put in the mouth. The contents can irritate the skin, eyes and mouth.

Some glow products contain a chemical called dibutyl phthalate (DBP). The liquid typically causes immediate stinging and a burning sensation in the mouth and eyes. 

Here are some tips from poison-control experts:

• If ingested, the bitter-tasting chemical will likely cause brief discomfort in the mouth. Thorough rinsing should help.
• If the liquid gets on the skin, wash it off immediately to prevent the child from rubbing the chemical in the eyes.
• If it gets in the eyes, it will cause redness and burning. Prompt irrigation is necessary.

Exposure to DBP may cause serious symptoms in pets. They can include drooling, gagging and vomiting.
