Here’s How the Powerball Is Making Sure No One Tampers With the Drawing

The Powerball drawing Wednesday night could give away a record-breaking $1.5 billion jackpot, and the people responsible for the show aren’t leaving anything to chance.

Florida lottery spokeswoman Connie Barnes told ABC News that the Tallahassee studio will implement a range of security measures to make sure the drawing is not tampered with, including keeping the lottery balls in a double-locked vault that is alarmed and sealed. Barnes also said that three people— a Florida Lottery security officer with the code to disarm the alarm, a Multi-State Lottery Association official with a key, and a person from an independent accounting firm with a second key— are needed to access both the drawing machines and ball sets.

According to the network, each lottery ball also goes through a series of tests before being put in service, which include being measured, weighed, X-rayed and density-tested at a state lab, followed by a second test comparing the results to statistical analysis. The verified ball sets tend to last two to four years, and they are tested every year until they are taken out of circulation.

Finally, all ball sets and machines used in Powerball drawings are randomly selected before they are used. Barnes also told ABC News that pre-tests are done to make sure the machines are “operating randomly.”
