WARD’S Crustal Stress Simulator |
| Dramatic Demonstration of Changes in the Earth’s Crust |
A turn of the hand crank on the unique stream table accessory moves a flexible belt floor of the sediment trough, causing an underlayer of clay and top layer of sand to raise two parallel folds. A stream, then a lake, then a water gap emerges. You can separate the clay and sediment for reuse. WARD’S Stress Clay and Sand-Gravel Mix is recommended. Size:35 1/2″L x 13 1/4″W x 3″H.
