Children and their parents had a blast at the UH Institute for Astronomy open house on Sunday.

They got to do several hands-on activities including putting a hot dog in liquid nitrogen.

The annual open house is all about showing kids that science and astronomy is fun.

“We all want kids in science and engineering. It’s not just stuff in books, this lets them see that they can do it hands on and even at their young age they can do it themselves,” said UH Astronomer Roy Gal.
