Amazing Anamorphic Illusions!

These are so simple but always so amazing to see.

I did 3 anamorphic illusions. Rubiks cube, a roll of tape and a shoe. Which one is your favorite? I like the shoe the best.

Oh and lets not for the kitty cat. Hyder thought she was anamorphic for a bit there.

I’ve included the images in this video for you to download and try yourself. Print them on 8.5 X 14. Cut the paper any way you’d like to add more of an effect.

Angry Birds Christmas Lights

What do you get when you take Angry Birds, the hottest mobile game ever, and combine it with the musical talent of Pomplamoose? You get 25,000 Christmas lights pumping to the Angry Bird Theme song covered by Pomplamoose.

Science! Corn Flour Fireball

Corn flour blown through a funnel produces an excellent fireball. This both looks cool and demonstrates some interesting science.

In any chemical reaction, the reactants must mix with each other significantly in order to increase the rate of reaction.

Here we demonstrate that corn flour on a spoon burns slowly, but blown from a funnel, the reaction is dramatic and violent. This is because the surface area where the reaction can occur is greatly increased.

Levitating Barbecue! Electromagnetic Induction

At the Palais de la Decouverte in Paris, they showed me this experiment where a 1kg aluminium plate is levitated above a large coil of wire that is being supplied with 800A of alternating current at 900Hz. This is by far the best demonstration of electromagnetic induction I have ever seen.

Back in London, I visited the magnetic lab of Michael Faraday in the basement of the Royal Institution. It was here that he did his groundbreaking work on induction. People had previously observed that current in a wire causes a compass needle to deflect, but more exciting was the prospect of using a magnetic field to generate current. Faraday created his famous induction ring by winding two coils of insulated wire onto an iron ring. When he connected a battery to one coil, a small pulse of current was induced in the other. When the battery was disconnected, current was induced in the other direction. This led Faraday to the conclusion that current was induced in the second coil only when the magnetic field through it was changing.

And if they hadn’t been wrapped on the same ring, Faraday may have noticed that the two coils repel each other when the current is induced due to the interaction of their magnetic fields. This is the same thing that is happening with the aluminium plate, except we’re using alternating current to create a continually changing magnetic field. This induces an alternating current in the plate, producing an opposing magnetic field which levitates the disk.
