Exploding disk cannons, slimemobiles, and 32 other projects for Saturday science /
Downie, N. A.(Neil A.)
Presents thirty-four science experiments of varying difficulty that can be completed in one day, including a rope ratchet motor, exploding laser spots, and a calculator communicator.
Includes bibliographical references (pages 283-288) and index.
1. Projectiles 1. Bursting Disc Cannon-learn about crack propagation and launch projectiles 2. Designer Demolition 2. Balloon Detonators-great for the end of parties & playing your 1812 overture CD 3. Slowly Exploding bolts-just the thing for your next Moon rocket 3. New Motors 4. Vacuum Engine or Negative Steam Engine-transmit power with nothing! 5. Rope Ratchet Motor-a motor transmission with a piece of string instead of gearwheels 6. The 50 cent stepper motor-a very simple version of the complex motors at the heart of much modern equipment 4. Pushing String 7. The Pullmetopushme-pull a lot of string backwards & you can push a bit of string forwards 8. Land-Jiggers-or try ice-jiggers and go fishing with Inuit 9. Power Strings-what could be a bigger blot on the landscape than rows of electricity pylons? Whistling electricity pylons! 5. Peculiar Vehiculars 10. Ekranoplan-the close-shaving aircraft-is it a razor or an airplane? 11. Aeroslug-keep your prop turning and don't run out of slime 12. Ball River-bobsleighs on ball bearings 13. Skidmobile-driving everywhere in a skid 6. Curious Controls 14. Wet Blanket Valve Flow Control-the enthusiastic control valve 15. Electrolytic Gas Pedal-an Edison Loudspeaker is re-used as a speed control 16. Piezistor-the transistor which the Victorians could have invented 7. Granules & Particules 17. Rice Grain Ski-jump-sporting activities for cereals 18. Niagara meter-shadows show flow 19. Magical Magnetic Flows-stir a little magnetism into your hourglass 20. A Balance of Air Blasts-sweep gold dust from your carpet, leave the dog hairs behind 8. Perceptive Illusions 21. Hovering Images-mirages appear with the aid of a rotating lenses & mirrors 22. Moire Microscope-no lenses, grids of tiny holes are all you need 9. Lasers 23. Exploding laser spots-laser scattering light show 24. Instant parabola spots-it's all done with smoke and mirrors (and a laser) 10. Telegraphic 25. Helidoodle-transmit images in spirals 26. Messages in Wriggling Lines-Morse pens and Chartagrams 27. Calculator Communicator-send messages using this binary teleprinter 11. Instruments 28. Human body posture meter : are you sitting comfortably?-this will meter will tell you if you are 29.
