First off, here is a CD burner literally. After a second or so sparks appear and shortly after flames after which it is wise to turn off to avoid magnetron damage in view of the lack of loading.

Aerogel is typically The resulting silica dioxide structure is sponge like with microporosity on a nanometer scale. It was discovered in the 's but came into the public eye with aerospace uses including Mars Rover insulation and as a comet dust collector with Stardust 2.

Basically two aluminium electrodes in a sodium bicarbonate solution will glow and sparkle with sufficient applied voltage. One electrode is aluminium foil and the other is an aluminium bar. Here's my take on what is happening.

If you insert an aluminium electrode in a solution then it will form an oxide layer and when the metal is positive will block current flow. This, as I understand, is the basis for electrolytic capacitors and the reason they are polarized.

Here we have two aluminium electrodes which is the equivalent of back to back electrolytics which are then non-polarized. Initially there is a lot of current flow e.

After a few minutes there is little flow even at VAC. Exceed this however and things start to happen fast. I interpret this as breakdown of the oxide layer with voltage.

There is a diffuse glow starting at about 60 VAC but the sparkling becomes more prominent with increasing voltage.

Note that the alkali solution boils rapidly with the heat. Eye protection is very important here. Spooky Cornstarch Inspired by a recent video I decided to do make my own cornstarch fun. Corn flour in Australia. Essentially cornstarch liquid is a fluid whose viscosity is rate dependent.

You can hit it hard with a spoon and it will strike it and bounce off, but can be spooned slowly and drip from a spoon. A real anti splash fluid.

On a flat plate under vibration the vibration is probably more marked at discontinuities and edges like a wave breaks at the seashore. This leads to bizarre effects with cornstarch which gets forced up into stalagmites, loops and bizarre writhing spooky shapes like pools of writhing undead Anyway it is very easy to do.

This is a common cooking ingredient. Get a small loudspeaker I used 4 inch, 4 ohm, 3. I guess the speaker can still be in its enclosure. Use a 6 VAC transformer or winding with a dropping resistor of 8 - 10 ohm 5 watt, or use a variac. Even use the other speaker of a stereo pair as a dropping resistor.

I needed about 2. Place some plastic cling film Gladwrap in Australia loosely over the speaker so that a spoonful or two of the cornstarch mix will sit closely applied to the speaker cone.

I did try a frequency generator and different frequencies but 50 Hz seems fine, particularly as it dries a little and the viscosity rises.

I tried this with a subwoofer and the results were a bit disappointing initially. The right photo shows only limited extension of the corn flour.

Removing the plastic had little effect until I got out the frequency generator and a W audio amp and picked out the resonant frequency of about 22 Hz where cone excursion was greatest and up to one inch.If you are a teacher searching for educational material, please visit PBS LearningMedia for a wide range of free digital resources spanning preschool through 12th grade.
