Origami started over 400 years ago in Japan but has spread throughout the world. You can create a paper creature from an ancient origami pattern, or just get a stack of paper and fold it, cut it, tape it, and glue it. There seems to be no limits to what can be made through the art of folding.
Ancient scholars discovered naturally magnetic lodestones over 2500 years ago. Physicists use magnetism often for their experiments. They can even be used to measure the magnetic field of the Earth! Just take some of your standard Silly Putty and blend in some black iron oxide. As far as experiments go, this is simple and safe, and the results look awesome.
Meteorologists seek to understand weather, but they do more than deliver the forecast. They collect data from all around to study the forces at work in the Earth’s atmosphere. They tirelessly track temperature, pressure, moisture, and movement, on a quest to predict the unpredictable.
