Flash Science is our newest Shopcast. These quick videos show flashy science experiments that can be done with everyday objects. All of these experiments are designed to be done by adults, or with careful adult supervision.
Beads on a picture create an instant low tech pointillist painting.
A piece of clear plastic shrinks and turns white with heat. A great way to re-use #1 containers!
The electric fields inside of a microwave cause sparks, heat, and even shrinks a bag of chips!
A bar of soap in the microwave grows to tremendous proportions.
You can light a bulb in the microwave (for a little while) and the electric fields in the oven will cause it to light!
A water bottle and a grill igniter make a ping-pong ball launcher.
This week, Kenn shows us how to build world’s simplest motor!
This week, Rachel shows us an awesome experiment which uses electricity to heat up the graphite in a pencil lead, making it glow very bright!
Goldenrod paper turns red when ammonia or other base is added. Rachel shows us how we can use this to write secret messages!
A grape makes a great dipole antenna, and makes a great (small and safe) series of sparks in the microwave.
Smoke from an extinguished candle makes a “fuse” that relights it.
The heat from a camera flash makes a puff of smoke from a black surface.
A pen with thermochromic ink is erased with heat and made to reappear when cold.
A small ball is placed in a funnel—and cannot be blown out.
A bubble on a stadium horn… Will it pop when the horn is played?
A plastic frame can be used to create square—and other unusual shape—bubbles.
A stream of air is used to levitate a small ball—and also a light bulb.
A water-filled balloon can be held over a candle or a torch, and not pop!
Fine steel wool will burn brightly with the help of a 9 V battery.
You can push a knitting needle through a balloon if you take certain precautions.
A stuffed animal saturated with alcohol and water can be set on fire, and touched while alight.
Using the power of air pressure to blow out the bottom of a bottle.
Passing a current through water makes hydrogen and oxygen gas, which fill a bubble that can be ignited.
Alcohol vapor in a plastic bottle is lit, giving forward propulsion.
We typically think of glass as an insulator, but it will conduct electricity if it gets hot enough!
A ground fault protected cable passes electricity through a pickled cucumber, this produces a surprising glowing effect in the cucumber.
A pencil lead and some batteries make a small plasma cutter that we use to etch a pattern in aluminum foil.
Some powdered sugar, a straw and a propane torch produce a flame, that is circus-like in its drama.
An internally frosted, large light bulb is dipped into a fish tank of water, and the total internal reflection effect produces ‘other-worldly’ consequences to how the bulb looks in the water. The bulb goes from white to a silvery orb. Turning the bulb on, produces a similar, but more alluring effect.
