Flash Science: Graphite Glow

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!

More...

Flash Science: Secret Message With Windex

Goldenrod paper turns red when ammonia or other base is added. Rachel shows us how we can use this to write secret messages!

More...

Flash Science: Flashy Grape

A grape makes a great dipole antenna, and makes a great (small and safe) series of sparks in the microwave.

More...

Flash Science: Flaming Smoke Fuse

Smoke from an extinguished candle makes a “fuse” that relights it.

More...

Flash Science: Heat Flash

The heat from a camera flash makes a puff of smoke from a black surface.

More...

Flash Science: Erasing With Heat

A pen with thermochromic ink is erased with heat and made to reappear when cold.

More...

Flash Science: What Keeps the Ball in the Cone?

A small ball is placed in a funnel—and cannot be blown out.

More...

Flash Science: Bubble Trumpet

A bubble on a stadium horn… Will it pop when the horn is played?

More...

Flash Science: Bubbles Squared

A plastic frame can be used to create square—and other unusual shape—bubbles.

More...

Flash Science: Arc of the Air

A stream of air is used to levitate a small ball—and also a light bulb.

More...

Flash Science: To Pop or Not To Pop

A water-filled balloon can be held over a candle or a torch, and not pop!

More...

Flash Science: Steel Fire

Fine steel wool will burn brightly with the help of a 9 V battery.

More...

Flash Science: Needle Through a Balloon

You can push a knitting needle through a balloon if you take certain precautions.

More...

Flash Science: Pouring Air

Carbon dioxide can be poured like water, extinguishing candles.

More...

Flash Science: Bubbles on CO2

Bubbles will float on a dense layer of cold carbon dioxide.

More...

Flash Science: Flame Hound

A stuffed animal saturated with alcohol and water can be set on fire, and touched while alight.

More...

Flash Science: Water Hammer

Using the power of air pressure to blow out the bottom of a bottle.

More...

Flash Science: Hydrogen Bubbles

Passing a current through water makes hydrogen and oxygen gas, which fill a bubble that can be ignited.

More...

Flash Science: Burning Bubbles

Propane bubbles can be held—and ignited—in the hand.

More...

Flash Science: Alcohol Rocket

Alcohol vapor in a plastic bottle is lit, giving forward propulsion.

More...

Flash Science: A Glass Conductor

We typically think of glass as an insulator, but it will conduct electricity if it gets hot enough!

More...

Flash Science: Electric Pickle

A ground fault protected cable passes electricity through a pickled cucumber, this produces a surprising glowing effect in the cucumber.

More...

Flash Science: Plasma Cutter

A pencil lead and some batteries make a small plasma cutter that we use to etch a pattern in aluminum foil.

More...

Flash Science: Sweet Fire

Some powdered sugar, a straw and a propane torch produce a flame, that is circus-like in its drama.

More...

Flash Science: Reflecting in the bath

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.
