Be careful, obviously, while swinging a hammer in a darkened room

For some reason that made me smile.

1) I loved the video of the 2lt soda + mentos
2) I wish my microwave was working and I had a grape right now.

I usually get annoyed at the slow motion replays that are on the Fail videos.
This time however, it added just the right finishing touch.

I remember seeing the cornflour/water one in an episode of Numb3rs!

The coke video was an excellent way to start the morning.

Ahh I actually jumped out of the way. I'm awake now

You'll have better luck if you microwave a tiny lit candle or a tightly rolled paper towel 'fuse'. Fire is technically already plasma but don't remind your party guests about that when you are busy impressing them.

Zhu's process involves absorbing the photon of sunlight in a plastic - in his experiments, pentacene - to produce a dark quantum "shadow state" from which two electrons can be retrieved, instead of just one.

He talks about plasma as "the fourth state of matter" as if there were four states. He neglects the fifth: Bose-Enstein condensate.

Yes, yes, but how about inverting the frequency and channeling it through the deflector dish?

Now I want to build a rocket with diet coke and mentos.

Make sure you aim it AWAY from a population center.

What a time to be out of grapes!

Ha yeah, I hear ya. But what I have in mind is building an actual rocket propelled by diet coke/mentos rather than a firing off a cannonball.

I may just take it down to the Niagara River and fire it at Canada

Well, plasma was the fourth state discovered, so it'll be "the fourth state of matter" even if we find 10 more.

I learned that one in 5th grade. After I learned about it I went home and got into the pantry, my mom came home from work and wondered what the hell I was doing with 2 boxes of cornflour and water

The coke bottle rocket video is the best example of Schadenfreude I've seen in a week.

There are so many possible states of matter (new window) that it really doesn't make sense to count them.

Here are some more home demonstrations you can do:

"Hot ice" (new window), an extension of the vinegar + baking soda one.

Make an electric motor (new window) from one magnet, one battery, and a piece of wire

Grow crystals (new window). The real way, not the 4chan "toxic gas cloud" way.

Make a glass of water suddenly change color (new window).

Draw holograms by hand (new window).

The Rubens Tube experiment should probably have made the list. Fire is, well, awesome.

It's safer, of course, to create plasma the old fashioned way: With gold wire and a 10kV power supply. The ozone will give you a headache, though.

There is no way i would show my Kid that grape plasma bit.

My roommate however...
