+ | ===== Hole in crown cork (Institute people only) ===== | ||
+ | |||
+ | The task here is, to get a tiny hole into a crown cork, without completely destructing it. | ||
+ | To do so, there is various stuff, which could be used. | ||
+ | The solution idea is to freeze a banana with the liquid nitrogen. (This must not be done by the students but by one of the tutors.) Then, the banana can be used as a hammer. | ||
+ | Then, a fixing pin can be sticked into a cork. Now, this can be used as " | ||
+ | With the banana-hammer, | ||
+ | |||
+ | |||
+ | ===== Interference with hair (Institute peole only) ===== | ||
+ | |||
+ | |||
+ | The task of this experiment will be to measure the width d of tiny objects (like hairs) with a monochromatic laser of given wavelength λ. To do this, one profits from the fact, that the position of the diffraction minima is the same as in a single-slit experiment whit a slit of the same width d. | ||
+ | If the students don't know the physics behind this experiment, provide them with the needed formulas to determine the width of the hair. If you have the time, you can also try to explain the physics in more depth, but this is not required. | ||
+ | |||
+ | A simple derivation of the corresponding formula $d\, | ||
+ | |||
+ | |||
+ | ===== Balloon rocket ===== | ||
+ | |||
+ | |||
+ | In this experiment, the challenge is, which studentgroup can build the best balloon rocket. | ||
+ | |||
+ | The idea is to tape a inflated balloon to a straw which is fixed on a long cord. Who reaches the furthest point, wins. | ||
+ | |||
+ | |||
+ | ===== Water rocket ===== | ||
+ | |||
+ | |||
+ | This is just a fun experiment. Some physical backgrounds can be found here: http:// | ||
+ | It is not necessary to discuss the whole principle of recoil in a too precise manner. One can give some keywords like: | ||
+ | Apart from this, the students shall have fun and if they wish, they can have a competition on who reaches the biggest shooting distance. | ||
+ | |||
+ | |||
+ | ===== Bridge and ship ===== | ||
+ | |||
+ | The task is to build an bridge over a gap of approximately 50-80cm. To do this, the students get nothing but 10 pages of paper. The winner is the one who builds a bridge on which one can put the most tealights. | ||
+ | The use of glue or any other aid is forbidden. |
