Sitting on a hard foam wedge on chairs during the school day reduced back pain in teens by 58% compared with those not using the wedge, says a report in the journal Physiotherapy.
Patrick's car careened back into David Ragan, flipping her hood over the windshield and shredding the left front fender as protective foam from the driver's side door flew onto the track.
Using cross links within the foam's particle arrangement, regardless of how much the structure is compressed, it'll spring back to the predesigned shape.
The rest of the vertical column is made from a material called syntactic foam - a solid made mostly of hollow "microballoons" - giving it enough buoyancy to float back up.
