A petri dish is a flat dish made of plastic or glass with a cover that is primarily used to grow bacteria. However, the petri dish can be used to view seed germination or for viewing small animal observations. Petri dishes fit conveniently under a dissection scope (stereomicroscope) and are often used as a platform for viewing any small objects. Other applications are possible as well.

An electric bicycle, also known as an E-Bike or booster bike, is a bicycle with an integrated electric motor which can be used for propulsion. There are a great variety of e-bikes available worldwide, from e-bikes that only have a small motor to assist the rider's pedal-power (i.e., pedelecs) to somewhat more powerful e-bikes which tend closer to moped-style functionality: all, however, retain the ability to be pedalled by the rider and are therefore not electric motor cycles. E-bikes use rechargeable batteries and the lighter varieties can travel up to 25 to 32 km/h (16 to 20 mph), depending on the laws of the country in which they are sold, while the more high-powered varieties can often do in excess of 45 km/h (28 mph). In some markets, such as Germany, they are gaining in popularity and taking some market share away from conventional bicycles, while in others, such as China, they are replacing fossil fuel-powered mopeds and small motorcycles.
