Can you predict what happens to the golf ball?

In this experiment we see that a golf ball is denser than detergent (it is also denser than pure water incidentally, which is why water hazards are so effective at ruining a golfer's day on the course). But, a golf ball is less dense than a saturated salt solution. Now the question is: if you pour the detergent on top of the golf ball in the salt solution, what will happen to the golf ball?

Special thanks to Duane Merrell for the idea, which I saw demonstrated at BYU back in February. Thanks to Emil Malmsten for excellent filming, and his Stockholm colleagues who were game to have a chat to me about this experiment.

A recent survey of scientific literacy in Australia found 30% believe it takes one day for the Earth to go around the sun. This video provides qualitative evidence for the finding from Sydney's Eastern beaches.

A bisected grape in the microwave makes plasma. But how does it work? A grape is the right size and refractive index to trap microwaves inside it. When you place two (or two halves) close together the fields interact with each other creating a maximum of electromagnetic energy where they touch. This creates heating, sparks, and plasma, which is further fed with energy directly by the microwaves.

Huge thanks to Hamza Khattak, Prof. Pablo Bianucci and Prof. Aaron Slepkov (unavailable for the call) for chatting to me and helping me understand the physics of this cool phenomenon.

Our mission was a unique one - to launch weather balloons up to 100,000 feet loaded with experiments, tracking devices and HD cameras. This is the result of our trip, produced for Catalyst on ABC1 http://www.abc.net.au/catalyst/

Mosquitoes are attracted to me and it's likely due to my genes.

Genome Wide Association Study for self-reported mosquito attractiveness:

The twin study showing correlated attractiveness is stronger for identical twins:
http://ve42.co/MossieTwins

Some things we know make mosquitoes more attracted to you:
Exercising, higher metabolism, higher body temperature, more body odor, being pregnant, type O blood, infrequent bathing, lactic acid, ammonia, acetone.

There are a number of folk remedies people believe protect them from mosquito bites like drinking alcohol, eating garlic, or taking vitamin B. These do not appear to provide any benefit in lab studies and in fact drinking alcohol is associated with increased mosquito activity because it causes blood vessels near the surface of the skin to dilate.

And apparently some of your attractiveness to mosquitos is simply genetic. This may be mediated through your immune system, which is what a lot of the genes identified were associated with.

I am nearing the end of a 6-week road trip filming for an Australian TV show called Catalyst (http://abc.net.au/catalyst). Along with co-presenters Anja and Simon, I have travelled from Perth towards our destination, Melbourne, picking up all the interesting science stories along the way.

Since we have been working long days I haven't had time to make any new Veritasium material. Instead I thought I'd share some things I have done for this show in the past, including narrating short 'factoid' segments like this one. Hope everyone is having a great holiday season and I look forward to getting back to Veritasium stuff in a few weeks.

2011 is the international year of Chemistry. But what do Australians know about it?

The solution to the question posed in the spinning tube trick video, that is - what would you see if looking at the spinning tube from below a glass table. The explanation of why only the X or O is visible will be the subject of the next video.

We’ve taken giant leaps and left our mark in the heavens. Now we’re building the next chapter, returning to the Moon to stay, and preparing to go beyond. We are NASA – and after 60 years, we’re just getting started. Special thanks to Mike Rowe for the voiceover work.

We are going to the Moon, to stay, by 2024. And this is how.

What have we accomplished and what's ahead in our mission to explore the Moon, Mars and worlds beyond? On Feb. 10, NASA Administrator Jim Bridenstine unveils the "State of NASA" and shares details of the FY2021 Budget and more.

Bridenstine shared that “President Donald Trump’s Fiscal Year 2021 budget for NASA is worthy of 21st century exploration and discovery. The President’s budget invests more than $25 billion in NASA to fortify our innovative human space exploration program while maintaining strong support for our agency’s full suite of science, aeronautics, and technology work."

“The budget proposed represents a 12 percent increase and makes this one of the strongest budgets in NASA history. The reinforced support from the President comes at a critical time as we lay the foundations for landing the first woman and the next man on the South Pole of the Moon by 2024. This budget keeps us firmly on that path."

NASA Astronaut Breaks Down Space Scenes From Film & TV | WIRED

Fifty years to the day that humans stepped on the Moon in a giant leap for humanity, three space travelers are launching to our orbiting laboratory. NASA’s Andrew Morgan, Roscosmos’ Alexander Skvortsov and European Space Agency’s Luca Parmitano will launch at 12:28 p.m. EDT aboard the Soyuz MS-13 rocket for a six journey journey to the International Space Station. Tune in starting at 11:30 a.m. EDT to see launch coverage:

Daniel Calveti 2017: El título de este nuevo cd es Habla sobre mí, es un congregacional de música cristiana, Alabanza y Adoración, tiene como misión exaltar el poder y la influencia de las palabras de Jesús sobre nosotros, cada vez que Jesús hablaba de transformación y esas palabras quedaron registradas en la Biblia para que todo aquel que la lee, la cree y la canta la pueda experimentar como el poder de Dios viene sobre sus vidas y circunstancias difíciles las cambia por milagros, cuando Dios puso en mi corazón hacer este disco fue intencional en hacerme saber que traía una unción de sanidad sobre la iglesia.

No puedo esperar cantar estas canciones públicamente y ver como Dios sana a las personas mientras cantamos.

Letra Completa:

De tu boca sale aliento
Que mi alma necesita
En tu palabra hay poder
Que trae vida a mis huesos

Jesús tu nombre es el verbo de aliento
Jesús tu nombre es el agua de vida
De tu boca sale aliento
Que mi alma necesita

Jesús tu nombre es el verbo de aliento
Jesús tu nombre es el agua de vida
Oh Jesús tu nombre es mi pan.

Tú hablas y el sordo oye
El ciego ve al oír tu voz
Grande es tu poder
Grande es tu poder, Jesús

Tú hablas y el cojo anda
Con tu poder el mudo habla
Habla sobre mi
Habla sobre mí, Jesús

Era ciego y ahora puedo ver
Sordo fui y hoy te escucho
Habla sobre mí, Jesús

Preso fui y hoy libre soy
Perdido estaba, mas hoy tu hijo soy
Habla sobre mí, Jesús
Habla sobre mi
Habla sobre mí, Jesús

Habla sobre mi
Habla sobre mi
Habla sobre mi

Habla sobre mi
Habla sobre mi
Habla sobre mí, Jesús

Era ciego y ahora puedo ver
Sordo fui y hoy te escucho
Habla sobre mí, Jesús

Preso fui y hoy libre soy
Perdido estaba, mas hoy tu hijo soy
Habla sobre mí, Jesús
Habla sobre mi
Habla sobre mí, Jesús

«Apocalipsis 4» es una canción congregacional con la que el salmista desea inspirar a la iglesia contemporánea a prepararse para ese glorioso día de adoración eterna delante de Dios, tal como se describe en ese capítulo del último libro de la Biblia. Para Daniel, es de suma importancia que la iglesia sepa qué es lo que va a encontrar cuando entre en la presencia del Dios de gloria.

Yo veo cielos, abiertos sobre mí,
Hay una puerta abierta
Sobre mis circunstancias,
Subo a tu trono y me postro ante ti,
Subo al sonar de tu voz de trompeta.

Muéstrame lo que estás viendo para mí,
Yo soy tu hijo y tú eres mi Padre.
Espíritu Santo, lléname, aclara mi visión,
Que yo vea el trono
Y al que está sentado allí.

Tú que cumples tus promesas, recibe
Mi adoración. Vuelvo a ti mi corazón,
Vuelvo a ti mi corazón.

Yo veo tu trono lleno, de sonidos y de estruendos,
Relámpagos que salen, y no contienen tu poder
Tus ojos ven toda la creación y tu luz

Alumbra la verdad, ante tu trono todo
Santo, Santo, Santo.

¡Oh, Oh, Oh, Aleluya!
¡Oh, Oh, Oh vive el Rey!
Yo veo tu trono lleno de sonidos
Y de estruendos,
Relámpagos que salen Y no contienen
Tu poder,
Tus ojos ven toda la creación y tu luz
Alumbra la verdad, ante tu trono todo
Santo, Santo, Santo.
¡Oh, Oh, Oh, Aleluya!
¡Oh, Oh, Oh, vive el Rey!
Recibe honra, gloria y poder.
Todo lo que existe
por tu voluntad es.

Santo, Santo, Santo
