HARRISONVILLE, Mo. (KSHB/CNN) - One school in Missouri is testing a bulletproof storm shelter in the classroom to help keep students safe.
It's been shot at with an AK-47 and armor-piercing rounds from a 30-06. No bullets penetrated the steel.
And even wooden 2 x4s have been blasted at the outside of this shelter at EF-5 tornado wind speeds.
Today, students got to grade the hide-away shelter.
"In case of emergencies we don't have to run somewhere," said Michelle Sloan, Harrisonville Christian School teacher.
It was tested in a classroom for the first time at Harrisonville Christian School, both as a tornado shelter and a bullet proof refuge.
"All you need to do is flip on the switch," said Mike Vogt, president of Staying Home Corporation.
The hide-away shelter bolts to the ground and expands from 17 inches wide to a space large enough for 30 students.
Sloan is happy with it.
"A lot of responsibility that we think of as teachers and what do we do to keep our students as safe as we can and right now it just feels like our best isn't good enough," she said.
Vogt and his team of engineers designed it.
"This is a new concept completely. There is nothing else like this. We have filed a patent on it," he said.
He hopes FEMA will help pay for them. One shelter costs about $15,000, but the interest is also coming from more than just schools.
"On the Mexican border for businesses looking for protection from Mexican Drug Cartels. Could this go in embassies around the world to protect the people that are inside the embassies," said Vogt.
Back at the plant in Harrisonville, production is ready to start.
