How can I make a bottle look like it's filled with liquid?

As mentioned, casting resin is exothermic as it cures. It is not going to get hot enough to warp the glass, but it could crack it if you were to fill the bottle and let it cure. Better to pour in smaller amounts and turn it to form layers like a slush cast.

Bubbles will happen if you mix air into the resin. Mixing and pouring bubble free is tricky and I have done prisms which presented challenges of their own due to the differing thicknesses at each end. The bottle is round and if you intentionally mix air into the resin, your end result will look like a carbonated liquid.
 
Thank you. That looks like a good product. It looks great on the Yoda hut but I'm not sure if it would be able to be used to fill a bottle or if it's just more for surface applications?
 
The idea of magic water is great.

I wonder what happens to jello after it passes its use by date? brown jello poured in a bottle would give the desired look.

The bottle that I'm filling is going to be part of my BTTF collection. It's a 1955 Pepsi bottle. The same one that Marty drinks from :)

I did wonder about jelly/jello but thought that it would probably dry out and crack after a few years.
 
perhaps fill it with soda and cap the bottle?
as i recall i remember having to use a bottle opener as near back as the 70's. there were no twist off caps yet.
brew your own beer equipment suppliers would have the capper device you seek.
 
The first thing I would do is head down to the local and take a peek in their bins. Snatch up all the clear beer bottles then wash and remove the labels. These will be your test subjects, the thinner glass will serve a good monitor over which methods can harm or even break glass. Try anything you think will work on the beer bottles first to prevent a screw up on the real bottle. And place them in some sort of box or tray incase of breakage/over flow of resin for easier clean up.

The paint suggestion from earlier could work if slightly modified. If you used the translucent paint meant to replicate stained glass you could do the coating method which is easier and quicker then resin.

You may also want to look into resins more common sold as artificial water for silk floral arrangements. It has a lower heat while curing then some of the other resins.

You could probably take off the writing on the back with acetone .
It is a faithful replica of the 1950's bottles... Though I cannot recall if that was the style used in BTTF.

Thank you for the link. They are nice but unfortunately not the same design as the one I have that matches the screen used bottle. It took a little while to find the right design. I need to also find a diet Pepsi can from 1985 and the design I need is almost impossable to find :wacko

A capper devise is a good thought. I'll look into that. Thank you.

I did think about glass paint as that does indeed have the right kind of see through look to it. What ever I do I will follow your advice and do a lot of testing first :)
 
and about the capper, if your area has a brew supply store just take your bottle and the cap with you there and they will cap it for free. Then you aren't stuck with a $20 piece of equipment you'll never use again.
 
Thank you. I'll look into that. If not then I should be able to make my own capper that will be good enough for the job.
 
one time at a place i worked, somebody ordered a weathered beat up old paint locker. rather than spend hours and hours making the thing look like the real thing, we just shipped them our old beat up used paint locker from the shop and made a killing.
sometimes the easiest and most often overlooked answer is the best....
how to make a bottle look like it's filled with liquid? heh....
 
Might sound like a dumb idea but if you coat the inside of the bottle of with some kind of brown paint or stain you could fill the bottle with hair gel.
