About This Product
Mounting the ring on a stand frees the teacher’s hands and keeps the setup steady while the ball is heated, which suits teacher-led sessions. Students see the hot ball held back by the ring and released again after cooling, a clear lesson in thermal expansion of metals. Educational Instrument can arrange export supply of the Ball and ring apparatus, with stand to Gabon, Georgia, United Arab Emirates, Costa Rica and South Sudan.
