For the third year, seventh- and eighth-grade science students demonstrated hands-on experiments in physics, optics and chemistry with a Halloween twist for younger pupils at the 2875 Holly Drive school.
A bucket of ooblek — a mixture of cornstarch and water — stood in for a slime pit waiting for students brave enough to stick in their hands.
Another experiment referred to as ghost’s blood showed how acidic and basic substances can reveal a hidden shade of red on paper, and a ping pong ball was levitated with a straw to show aerodynamic principles.
Science teacher Shelley Ontis said the series of Halloween science experiments has become a popular tradition and an easy way to get younger students interested in science.
Nearly 600 kindergarten through sixth-grade students went through the lab Wednesday, Ontis estimated.
