Death Grips is an experimental hip-hop group that recently cut their show short after audience members reportedly threw glow sticks and other objects at them. Glow sticks are popular for their simplicity and versatility, but they contain chemicals that should be handled and treated with respect. Some glow products use a chemical called dibutyl phthalate, while others contain a small glass vial inside the plastic tube that contains a mixture of hydrogen peroxide in phthalic ester, and outside of the glass vial is another chemical called phenyl oxalate ester.

The ingredients or materials of the glow sticks that were thrown at Death Grips are not specified in the search results. However, it is worth noting that throwing objects at performers on stage is a dangerous and disrespectful behavior that can cause harm to the performers.
