| PROF BUNSEN (SW) - SINGING RODS SET | This amazingly simple demonstration will bring to life complex concepts such as resonance and natural frequency of vibration! Hold the rod in the middle with one hand, apply rosin to the thumb and forefinger and slide your fingers repeatedly along the rod to make the rod resonate at A high pitch. Excellent for discussing nodes, anti-nodes, wavelength and frequency. Included: Two aluminium rods of different lengths, A bag of rosin, Prof Bunsens classroom notes. Age: 12+ Code: PBSS01.

| RUBEN'S TUBE (FLAME TUBE) | Comprises A 2metre long x 75mm diameter aluminium tube with A 5watt speaker at one end and the other end blocked except for A connection where natural gas can enter. Along the tubes length are approximately 200 holes. When lit the gas flames dramatically show standing wave patterns created when the output of A signal generator is connected to the speaker, also known as the standing wave flame tube, or simply flame tube, demonstrating A standing wave and showing the relationship between sound waves and sound pressure. Instructions supplied. *Quote from A physics teacher: The best device on the market for showing standing waves in tubes." Code: CREBSRU.
