The Washoe County Sheriff's Office responded to Rancho San Rafael Park with a bomb squad this morning after receiving report of suspicious plastic bottles filled with liquid.
The sheriff's office says park rangers found the bottles while doing maintenance.
A bomb squad and RAVEN helicopter were called out to set up a perimeter as a precaution, but deputies say a chemical reaction in the bottles had already caused them to explode harmlessly.
Deputies say they have discovered similar explosives over the past year- and they can be potentially dangerous.
"For those that are making them, please it looks like a harmless prank but it is serious and it can harm persons and damage properties," says Sgt. Jack Buell.
Deputies encourage the public to call them whenever they see anything suspicious.
