{"product_id":"wp-dcd-10001398198","title":"Air-Supported Spring Oscillator for Physics Education","description":"\u003cp\u003eThis physics apparatus provides a visual representation of simple harmonic motion and wave mechanics. It features an air-supported spring oscillator system that uses a transparent hose to introduce air, minimizing friction along the track for smooth movement of the transparent sliding block. A visible spring assembly reacts to applied forces. The instrument includes a horizontal scale beam with centimeter markings for measuring displacement. It is mounted on a stable blue rectangular base with black posts. Dimensions: 30 cm length, 9 cm height, 10 cm width.\u003c\/p\u003e","brand":"World Products","offers":[{"title":"Air Cushion","offer_id":50414301511919,"sku":"dcd-30003967933","price":4.03,"currency_code":"USD","in_stock":true}],"url":"https:\/\/landmarks.builders\/products\/wp-dcd-10001398198","provider":"World Products","version":"1.0","type":"link"}
