Can you predict what happens to the golf ball?

Goes up: http://bit.ly/buoyGoUp

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.

Newton's Law of Universal Gravitation can be summarized as "all mass attracts all other mass." But if this is true, why don't we notice the gravitational force of attraction between everyday objects? The reason is because the gravitational force is quite weak.

How does a sailboat work? The standard idea is that the wind pushes the sails from behind, causing the boat to move forward. Although this technique is used at times, it is not the most efficient way to sail a boat (and it means the boat can never go faster than the wind). Lift is the key mechanism driving a boat forwards. As air flows over the sails, it moves faster over the outer side, creating lower pressure than on the inner side. This produces a force which is mostly to the side and a bit forwards. Lift on the centerboard pushes to the opposite side, cancelling the sideways force and adding a forward component of force to the boat.

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.

March 26 segment on live TV talking about solar storms and my upcoming trip to the Great White North. As you watch this I will probably be on a plane high over the pacific.
PS a student recently told me that my hair to beard ratio is a bit off and watching this clip I tend to agree. However, it is still -20 C at night in Alaska so I'll need all the insulation I can get.

In the next eight minutes, you’ll experience a twenty-five-and-a-half-day mission from roll-out to recovery of the first integrated flight test of NASA’s Orion spacecraft and the Space Launch System rocket, launching from the agency’s Kennedy Space Center in Florida. This uncrewed mission will be the first in a planned series of exploration missions beyond the moon, signaling what astronauts who dare to operate in deep space will experience on future flights.

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.

Special thanks to William Shatner for lending his voice to this project.

Letra de Sólo Tu Gracia, de Daniel Calveti
(Señor, estamos agradecidos por tu gracia,
porque tu gracia nos ha arropado,
nos tiene aqui hoy, te amamos Señor.

Solo tu amor nos ha sostenido,
y hoy podemos cantar de tu tierna gracia,
te amamos a ti Señor.)

Solo tu gracia es la que abre puertas
Solo tu amor es quien me sostiene
Y yo no entiendo
Porque me escogiste habiendo muchos aquí
No se lo que pasa pero gracias te doy
Porque en tu mirada me viste tu a mi
Y habiendo otros que hagan lo mismo
Me escogiste a mí

Solo tú abres puertas que yo no entiendo, no.
Y si otros me preguntan porque estoy aquí
Yo les contestaré:

No es por mis fuerzas,
No es por lo que sé hacer
No es por lo que tengo
Es por tu tierna gracia
Tu tierna gracia
Tu tierna gracia
Y nada más

(Si Dios te ha dado algo, no es por tus fuerzas
solo es su gracia
no importa en que posición estés
no importa todos los bienes que puedas tener
es su gracia que te ha llevado allí.
Solo hay que tener un corazón agradecido
y decir: Señor, es tu gracia,
es tu gracia que nos sostiene.)

No, no es por mis fuerzas,
No es por lo que sé hacer
No es por lo que tengo
Es por tu tierna gracia
Tu tierna gracia
Tu tierna gracia
Y nada más.

Letra de Integridad de Daniel Calveti

Por Un Deseo Egoísta
Se Puede Perder Un Hombre
Por Un Deseo Egoísta

Con La Tentación No Se Juega
A La Tentación No Se Puede Reprender
A La Tentación Hay Que Salirle Huyendo
Cuida Tu Integridad Y También A Tu Familia

Por Un Deseo Egoísta
Cuando Vio A Betsabé
Bañándose En Su Desnudez

Por Un Deseo Egoísta
Sansón Pidió Prisión
Fue Su Perdición

Con La Tentación No Se Juega
A La Tentación No Se Puede Reprender
A La Tentación Hay Que Salirle Huyendo
Cuida Tu Integridad Y También A Tu Familia

Integridad Es Lo Que Quiere El Señor
