4-The Earth Quake Proof Bed

A Chinese man named Wang Wenxi has designed an earthquake-proof bed. This high-tech bed can automatically turn into a strongbox to help people survive an earthquake. And the bed’s thick frame can support a roof and the extra space inside its thick boards can store essential foodstuffs like canned goods and life sustaining water. They can help people survive for several days before being rescued, Wang said.
“I experienced the Xingtai and Tangshan earthquakes giving me more understanding of such natural disasters,” the retired 66-year-old said.
