SAFETY TIPS FOR TEA BAG ROCKET
• Flammable surfaces: DO NOT light tea bags on a flammable surface. Experiment should be conducted on a fireproof surface, like a metal pan.
• Smoke detectors: Do not light tea bags under or near smoke detectors
• Safety Glasses: Safety glasses should be used
• Touching fire: Do not allow anyone else to touch the lighter or the burning tea bag
• Falling ash: Be aware! Some ashes may be produced from the teabag, and they may fly into the air.

The universe is microwaving itself. A mystery signal discovered in the 1960s led to a Nobel prize.
In this video, Dianna explores one of the most mysterious discoveries in physics - a constant microwave signal that seemed to be coming from everywhere in the universe. It turned out to be light from an unusual process 13.8 billion years ago.

There’s a factory in Europe that makes antimatter! It’s the rarest, most expensive, and potentially the most dangerous material on earth. Scientists don’t know why this material is so rare. Anti-atoms took 72 years after we discovered antimatter to make. Why?

Current estimate of Antimatter, courtesy of Elise:
Stefan Ulmer made a back-of-the-envelope calculation based on energy and power consumption. The explanation goes as follows:
1. CERN produces 3e7 antiprotons per AD cycle or about 1e15 per year
2. This is about 1e15*1.67e-27kg = 1.67 nanogram per year
3. 1 gram of antiprotons has an energy (E=mc^2) of 9e13 Joule
4. The efficiency of the antiproton production process is 1e-9, so you need a billion times more energy: 9e22 Joule
5. The cost of power for CERN is 1kWh = 3.6e6 Joule = 0.1 euro
6. So that would make 0.1/3.6e6*9e22 = 2.5e15 euro
7. And it would take CERN 6e8 years

How We'll Find the Aliens in Our Solar System! | STELLAR
110719 Like and subscribe. This is an archive, check the link in the end if you are owner. Thank you to Draper and its Hack the Moon initiative for supporting PBS Digital Studios | Learn more at https://wehackthemoon.com.
I got to visit two awesome upcoming NASA missions searching for life in our solar system! The Mars 2020 rover mission targeting the Jezero Crater and the Europa Clipper reconnaissance mission to explore one of Jupiter's moons due to launch in 2023. I explore if alien life is possible, where we're most likely to find it and why.
I know, this video is a bit different from most Physics Girl videos. It's part of a PBS miniseries called Stellar, done in collaboration with Matt O’Dowd from @PBSSpacetime and Joe Hanson from @It'sOkayToBeSmart. Over six episodes we travel to telescopes, go inside space research centers, and chat with amazing scientists. Next up is Joe's episode where he explores where life might be outside our solar system.

We’ve been waiting to verify the existence of Gravitational Waves for over 100 years and I actually got to go to LIGO to see exactly how they proved it!
I know, this video is a bit different from most Physics Girl videos. It's part of a new PBS miniseries called Stellar, done in collaboration with Matt O’Dowd from @PBSSpacetime and Joe Hanson from @It'sOkayToBeSmart. Over six episodes we travel to telescopes, go inside space research centers, and chat with amazing scientists. Next up is Joe's episode where he visits one of the telescopes that was part of world-spanning Event Horizon Telescope.

This edition of the Physics Girl Everyday Mysteries series is a physics experiment uses a quirk of the voice and your vocal cords. Try it at home!
Prof Joe Wolfe’s acoustics website: http://newt.phys.unsw.edu.au/music/
Intro chapter on the voice: http://www.animations.physics.unsw.edu.au/waves-sound/human-sound/index.html
Wade et al paper on soprano singing through resonances: https://asa.scitation.org/doi/abs/10.1121/2.0000354
More on vocal tract resonances: http://newt.phys.unsw.edu.au/jw/soprane.html
https://www.ncbi.nlm.nih.gov/pubmed/15532674
More facts: Most objects have a number of different resonant frequencies. The first resonance of the pipe were were using was around 70 Hz, which was lower than any of us could sing. A bass singer could hit that note, but were were singing in the range of the second and third resonances of the pipe.
No longer compiling your pipe singing submissions, but feel free to tweet me your attempts! @thephysicsgirl
