7D20.10 | mousetraps | PIRA 500 | |
7D20.10 | mousetraps | 7D20.10 | 56 mousetraps in a cage are each set with two corks. |
7D20.10 | mousetrap chain reaction | MPa-1 | A large number of mousetraps set with two corks each in a large cage. |
7D20.10 | mousetrap chain reaction | Disc 25-15 | Ping pong balls on mousetraps. |
7D20.11 | better mousetrap | AJP 48(1),86 | An electronic mousetrap array that can be used as a single event "bomb" or a continuous self-sustaining nuclear reaction. |
7D20.11 | mousetrap improvments | AJP 31(1),62 | Attach
groups of six mousetraps to a hardwood block. The spacing between the blocks
can be varied to produce subcritical, critical, or supercritical assemblies.
Place two wood blocks on each trap. |
7D20.12 | nuclear-disintegration model | A-65 | A ball rolls down an incline and hits a group of balls in a small potential well. |
7D20.15 | match chain reactions | PIRA 1000 | |
7D20.15 | match chain reactions | 7D20.15 | |
7D20.15 | match chain reaction | AJP 51(2),185 | Matches
are spaced differently in two perpendicular rows. Light the match at the
junction and the entire row with the smaller spacing ignites. |
7D20.20 | dominoes chain reaction | PIRA 1000 | |
7D20.20 | dominoes chain reaction | 7D20.16 | Knock down a row of dominoes of ever increasing size. |
7D20.20 | domino "chain reaction" | AJP 51(2),182 | A
whisp of cotton knocks over a small domino starting a chain reaction in which
each succeeding domino is 1 1/2 times larger in all dimensions. |
7D20.30 | uranium model | 41-2.12 | A sphere contains
internal mechanisms to eject two balls (electrons) after a ball is dropped
in (thermal neutron.) Pictures, Construction details in appendix, p. 1378. |
7D20.31 | U235 fission model | 41-2.13 | A wooden
sphere flies apart and ejects two wood balls and an iron sphere when an iron
sphere is dropped in. Pictures, Construction details in appendix, p. 1380. |
7D20.35 | fission model - liquid drop | AJP 51(2),185 | Probe a motor oil drop in alcohol/water to induce "fission". |
7D20.40 | moderation of fast neutrons | 41-2.6 | The
moderation of fast neutrons in paraffin yields both fast and thermal neutrons
shown by shielding the boron counter with a Cd sheet and detecting thermal
neutrons from a second paraffin block. |
7D20.41 | water model xenon poisoning reactor | 41-2.11 | A water flow model of the behavior of a thermal neutron reactor with xenon poisoning. |
7D20.60 | resonance absorption of gamma rays | 41-2.8 | Model of resonance absorption of gamma rays consists of an electromagnetically driven tuning fork and audio oscillator. |
7D20.90 | nuclear explosion effects | AJP 50(7),586 | An introductory level summary of the physics of a nuclear bomb explosion and the effects on humans. |
