About This Product
After the air is pumped out, two students gripping the metal handles will find the halves very hard, if not impossible, to pull apart. Open the stopcock to let the air back in and they separate easily, which makes the role of atmospheric pressure plain. The sturdy metal handle on each half gives students something to pull on during school and college physics demonstrations. School Educational Instrument can supply the Magdeburg Hemispheres Steel to schools and colleges in Qatar, South Sudan, Seychelles, the Bahamas, Palestine and Sri Lanka.
