  • Pick up heavy weights easily with a simple pulley system

    A simple 'pulley' consists of only a rope that is looped around a support (usually a wheel). More complex pulley systems exists, but let's first get more familiar with the science behind pulleys with the following science experiment.

  • Make matchsticks move without touching them

    Surface tension makes the surface of a liquid seems as if it has a thin, elastic skin over it. In the following experiment, let's study how the surface tension of water can be weakened or strengthened by various substances.

  • Make a pendulum bowling game

    A 'Pendulum' is a rod or a string with a weight called a 'bob' on the end. Pendulums are often used in clocks to help keep the time, but can also be used in a fun game.

  • Have fun with the cartesian diver experiment

    Water, similar to air, is a fluid. According to Pascal's principle: when a force is applied to one point of a fluid in a closed container, the force is transmitted equally to all parts of the fluid. Try the...

  • Prove you are stronger than your friends with a simple pulley system

    Do you think you are stronger than two of your friends? No? You may be stronger than you realize! With a little help from a simple pulley system designed to magnify effort, or pull, you may just be able...

  • Make a spool ‘walk’ with the energy stored in an elastic band

    Two types of energy exist: kinetic energy is the energy of moving objects and potential energy is stored energy that has the ability to change into kinetic energy. Elastic energy contained in a rubber band is a type of...

  • Study how fire use up air when burning

    A fire cannot burn without air or 'oxygen'. A fire that is not burning well can often be helped along by blowing or fanning it, so that more air reaches the fire. Air or 'oxygen' is also used up...

  • Study how air fills spaces that look empty

    Air makes grass or trees sway, moves the clouds around or trap water in a funnel by filling spaces that we perceive as empty. We will use the last example to illustrate this, in the following science experiment.

  • Drive a sailboat with this fun science experiment

    Have you ever wondered how a sailboat can seemingly turn in any direction even though the wind only comes from one side? Let us do the following science experiment to better understand how a sailboat harness the power of...

  • Make a windmill do some simple work for you

    Early windmills used the wind to turn blades that rotated grindstones inside a mill. Various grains such as wheat and corn were ground with these grindstones to produce flour for baking bread. These days, a type of 'windmill' is...
