Bicycle pumps have several applications in a physical science classroom. The hand-held bicycle pump is an excellent and inexpensive choice for pumping up water rockets. Use the Bicycle Pump with Gauge and Release Valve for precise quantitative pressure measurements when studying Boyle's law. This bicycle pump is perfect for the Pressure Bottle Demonstration (AP5930), Boyle's Law in a Bottle Laboratory Kit (AP6855), and Absolute Zero Device (AP4531). Gauge range: 0-260 psi. Both bicycle pumps are made from durable aluminum and will last for years.
