how do i make a hollow, see-through sphere? Answered



See the varied answers? People need more information:

How big?

How thick?

What does it need to contain?

Will it be under any sort of load?

How long do you want it to last?

Sorry about the lack of info.

I tried the soapy bubbles but they exploded. lol

I have a crazy idea of making shields for my Star Trek Enterprise model.

Something that would engulf the whole ship or partial shields.

I'm trying to figure out the best way to go about this.

I got torpedoes :) but no shields :(

Thanks for the help

Dip bubble wand into the soapy bubble solution, so as to form a film of bubble solution on the wand. Then move that film, on the wand, near to your mouth. Then gently blow.

The spheres produced via this method are very delicate, and they don't last very long, but they are pretty to look at.

I think the Wikipedia article for "Iridescence" has a picture of some of these, what they call, "soap bubbles"


in other words, an aqueous solution of sodium stearate.

Well, I think we both agree that the punchline to this joke is, "soap bubbles."


you could use low pressure air. To inflate a membrane of C₁₇H₃₅COONa, or sodium stearate. This may, however be more fragile than you want.

Somewhere, I think it was in the old "Amateur Scientist" column in Scientific American, there was a piece about blowing permanent bubbles, possibly with model aircraft dope.

worth a try. I think that "shoe goo" adhesive might work, too.

Clear casting resin and a spherical form like a xmas ball.
Rotate on a machine as used for chocolate forms and you are good to go.

Pour casting resin into a tennis ball and spin it in a drill.

vacuum form in 2 halves


Blow mold (Google it)


Cast it in 2 part plastic.
