Can I do this myself? I'd like give a toy present to my kid that's "been in in space". I'm sure she'll love it.
Are there any instructions/tutorials on what I'll need for this? All I've heard is you need a camera, a phone with GPS and a box (styrofoam box?) to hold those, and a helium filled balloon.
I don't know what kind of balloon and what software to track the GPS signal of the phone via my PC where I'm at, how to put them all together to avoid breaking, what kind of balloon to use, what kind of toy (material) and what kind of camera will be fine at that degrees and not break or get damaged, etc.
PS. I'm fully aware of the legality of this where I'm at, what authorities I should contact and where to release the balloon and what meterological website to use to caluclate the approximate area the box will land to avoid it falling on someone's property, road, etc.
Many thanks.

I understand most of members here cant answer some of my question, but I think you will at least know what kind of balloon(s) to use. And I see nowhere else to ask this.

Amazing !!!!

I have no idea about the technical bits for this, but thanks for putting up and sharing a great video.......I loved it

Can you guys at least guess what kind of balloon is used and where I can get one?

A 4.5 ft neoprene balloon, or maybe the 5.5 ft

Thanks Graham.
I cant find out what "neoprene balloon" is when I google it.
I found some on eBay. Is it the same as "weather balloon". Some items on eBay are named the same.

Can "normal" balloons be used? Or are they different and/or too thin and will pop at lower altitudes? Thanks.
