1N22.00 - Rockets

Code Number:
1N22.00
Demo Title:
Rockets
Condition:
Good
Principle:
Action & Reaction
Area of Study:
Mechanics
Equipment:
Air Powered Rocket, Rocket with Solid Fuel Engines.
Procedure:

Video Credit: Jonathan M. Sullivan-Wood.

Connect the bicycle pump to the air powered rocket stand.  Set the stand at the desired angle.  Insert either the low, medium, high, or super thrust washer onto the stand and position the rocket.  Start pumping with the bicycle pump and when the correct pressure is reached the rocket will launch automatically.

CAUTION: This rocket is capable of reaching 125 feet in altitude.  The low trust washer is probably the one to use in the lecture rooms.  Even then you will probably hit the ceiling.

NOTE: Make sure you aim this at an unoccupied portion of the lecture room!!

The platform may be used to show how a rocket works.  Place several students on one end to act as the astronauts or payload.  Have 4 or 5 students stand on the other end of the platform in a single line getting ready to step off the platform.  As each student steps off the platform, the platform should be propelled in the opposite direction.  Note that the "rocket" accelerates a little faster each time a student steps off.

NOTE: The solid fuel engine rockets can ONLY be used outdoors.  Insert the desired engine in the rocket body and insert the cone with the parachute in the other end of the rocket.  Ignite using the electric igniter which can be found with the rocket car (1H1030).  Depending upon the rocket engine used up to 400 foot altitude is possible.
