The Reaction Research Society conducts complex amateur rocket projects, utilizing solid, liquid, and hybrid propellant technologies. The Tripoli Rocketry Association sanctions some amateur activities, which they call "research rocketry," provided certain safety guidelines are followed, and provided the motors are of relatively standard design.

Gilbert cloud chamber, assembled An alternative view of kit contents. The lab contained a cloud chamber allowing the viewer to watch alpha particles traveling at 12,000 miles per second (19,000,000 m/s), a spinthariscope showing the results of radioactive disintegration on a fluorescent screen, and an electroscope measuring the radioactivity of different substances in the set.
Logo of the program. The REXUS/BEXUS (Rocket Experiments for University Students / Balloon Experiments for University Students) programme is a cooperation between the German Aerospace Center (DLR) and the Swedish National Space Agency (SNSA) that allows students from higher education institutions to study experiments on board sounding rockets and stratospheric balloons.

The canister may be embellished with paper fins to resemble more closely a real rocket. [1] Various experiments and lessons can center around the use of a bicarbonate rocket. For example, students are sometimes asked to experiment with the amounts of water and Alka-Seltzer to find the combination which propels the rocket the greatest distance.
Bicycle safety is the use of road traffic safety practices to reduce risk associated with cycling. Risk can be defined as the number of incidents occurring for a given amount of cycling. Some of this subject matter is hotly debated: for example, which types of cycling environment or cycling infrastructure is safest for cyclists.
The term 'safety bicycle' was used in the 1880s for any alternative to the penny-farthing. The front and rear wheel were not necessarily the same size. [3] Later historians began to use the term in a more restricted way for the design that was a direct ancestor to most modern bicycles.
