By asking questions about our experiment we can begin to learn something about these problems. One of the problems that scientific experiments like this have is what is referred to as a scale problem our experiment is much smaller, slower and colder than real meteorite impacts. However, the immediate and perhaps more spectacular effects are the large ripples, or tsunamis that spread out rapidly from the impact centre. In a real impact, this could result in huge volumes of water vapour in the atmosphere. The meteorite (our pebble) impact in the pool sends a fair bit of water high into the air. Land-based impacts can also generate lots of heat, but this is a bit more difficult to simulate here. Note that the crater will also have a high rim made up of material thrown out during the impact. Flour is also thrown into the air in the case of a large meteorite impact the dust will reach many kilometres into the upper atmosphere and have a major influence on global climate (it will tend to block sunlight). In the case of the flour, the red pepper (as long as your aim was good) will spread out and give you an indication of how far the ejecta has been moved from its original spot. In the real world, earth materials (rocks, soils, trees, water) are ejected (thrown up and out) on impact. The slow motion allows you to see what happens to the water and flour on impact.įour short video clips show the results of 3 experiments in the flour box, and 1 in the pool.

You can then edit the video, add a title and captions in Windows Movie Maker or if you have it, something a bit more sophisticated.

There are several free Slow Motion Apps available that you can use to record the impact. I recorded the impact in water (a swimming pool) and in the flour box on my Tablet. When you’re finished with the flour you can spread it on the compost, or if you have kept your experiment very clean, make some spicy cookies with it. Try to hit this red spot with the pebble, dropped from about 2m height (use a tall person to help you, or a chair or step-ladder).

The red helps to delineate the shape of the ejected flour. I created a small circular area of red pepper in the middle of the box.

You can also demonstrate the impact in a bucket or pool of water.įill the box with flour until it is about 6-8cm deep.

A small amount of darker coloured powder – I used cayenne pepper because it has a good contrast against the white flour.

A couple of kg of (cheap) flour or something similar that is dry and really finely powdered.

A small box with sides about 6-10 cm high (shoe box, wood or plastic tray).

You can make your own crater easily with some pretty basic equipment and what’s more you can record it as images or videos on your smart-phone or tablet. In this experiment you can try to duplicate some of the things that happen during a meteorite impact. More recently in 2013 a smaller meteor explode over Russia Make you own meteorite crater It is generally thought to have been caused by an exploding meteor no crater has ever been found. On Ja massive explosion in eastern Siberia flattened trees over an area of about 2000 square kilometers. In the less distant past (a mere 50,000 years ago) a meteorite estimated to be about 45m in diameter and traveling at 20km/second (= 72,000 km/hour) crashed into the Arizona desert leaving a crater about 1600m wide (the Barringer Crater).Ĭheck out this short video on the solar system and meteorites. On earth, there have been some very big impacts that have led to extinction of all manner of life forms – perhaps the best known is the probable impact about 65 million years ago that hastened the demise of the dinosaurs. With just a small telescope you can see that the moon is peppered with craters. Meteorites, comets and asteroids have hammered earth, the moon and all the other planets since our solar system began, about 4.6 billion years ago. There are also many interesting questions we can ask of our experiments with craters, like “ how do they compare with real craters?” Meteorites in earth/solar system history
