The son asks impossible questions, the dad tries to answer.
This led to them sending a video camera carried by helium balloon up to 100,000ft into space.
Both very cool, and some great (video) photographic images from space.

Made clickable link -- I do think I've seen something (here or at NASA) about this before ... |

This was a great example of ingenuity. I saw a site about that about six months ago.

| By the way, that's what happens to human body at that altitude if we don't wear pressure-suit... we explode :P |

A group of MIT students did something similar a few years ago. They took still pics and used a foam beer cooler.
In the U.S. if your payload weighs less than 4lb, you don't need permission or a license from the FAA. Though it is a good idea to let them know and file a "Notice to Airmen" (at least I think that's what it's called) |

I'm surprised the FAA didn't come down on them hard so this doesn't become a common incidence. These balloons aren't controllable in flight, they can land anywhere the wind takes them. Does your insurance cover this? |

The amazing part is how easily the average Joe can obtain the assets to achieve such a goal. Granted there was probably over a grand worth of equipment on that balloon, but it was all retrieved safely and able to be reused.
The same mission would have cost NASA millions only a decade or so ago.

*Wondering if a couple of large model rocket motors could get it up to escape velocity after the balloon bursts.*
Either way, we should have a "Put a camera in space" challenge perhaps with a 6 month deadline.

haha, I'm wondering what it would take to get the camera to 11.2 km/s (escape velocity from earth)... And then again, how to retrieve those images :-) |

The escape velocity at the Earth's surface is 11.2km/s - That's based on the earth's radius of 6,378km
The balloon went to a height of 19 miles, which is 30km. This gives us a new 'radius' figure of 6,378km + 30km = 6,408km Plugging that into the equation gives an escape velocity of 11.15km/s
So a negligible change.
ETA: It's not exactly rocket science. har har har.
