A Proposition 100-inspired "flash mob" broke out Sunday at Park Place mall.

More than 100 supporters of Proposition 100, the 1-cent-per-dollar sales-tax-increase plan, assembled without warning - at least to unaware shoppers - in the mall's food court at 3 p.m. to dance the Macarena and sing "Vote Yes on 100" to the tune. It was over in minutes.

Some of the participants removed button-down shirts and T-shirts to reveal white T-shirts with "Vote Yes on Prop. 100" painted on them as they got up from their tables to dance.

The food court was fairly crowded Sunday, making it hard for people to hear the group's message.

"Our state's at the bottom on education," the group sang to the tune of "Macarena." "It's hurting the kids in our population. Elected officials are out on vacation. Vote yes on Prop. 100."

Voices for Education, a Tucson-based education-advocacy organization, threw the so-called mob together.

People representing Tucson, Catalina Foothills, Amphitheater and other school districts attended the event.

About Proposition 100

Proposition 100 is a temporary 1-cent-per-dollar sales-tax increase that Arizona voters will decide on May 18.

If it passes, total sales taxes for Tucsonans will rise to 9.1 percent, or 9.1 cents per dollar.

The tax would raise an estimated $1 billion - and two-thirds of the money would go to primary and secondary education.
