Shrink wrap for bottles - kids school project need help

[zukracer]

the goal is to seal what is in the container (liquid/ambient air/not sure) from the outside ambient air/moisture. They want to create a "control" so to speak and then leave the other bottles without a seal but closed and then open to demonstrate that over time moisture will evaporate from the open one and then to also determine what changes the other has even though it is closed but not sealed. The seal needs to be air, more importantly moisture proof. All needs to be kid/school safe so the thought of shrink wrapping the top of the bottle was that it is quick/easy and only requires a hair dryer

you could effectively use warm water when filling the bottles doesn't have to be tremendously hot for this to work when you seal it up pull it from the water that should be enough considering these are plastic bottles. Otherwise silicone on the cap threads so it isn't too messy should work.

and there you have it.....You cant tell me you dont have some duct tape laying around.

oh I have some gorilla tape, its like high test duct tape

All great suggestions, I think the teacher was aiming more for the real life look/feel rather than something the kiddos will find in most any of their garages (dad's science studies and other forgotten crap in the garage )

They have been talking about things spoiling, not eating/touching things that are or have gone bad, etc. Think the end goal is to show them "this is how it comes from the store" and then "this is what happens when it goes bad" and of course demonstrate how things affect it (open vs closed).

I'll tell ya it was easier when i was in school, they just said try it, if you live it was ok if you get sick the nurse is down the hall

2 things:

A flat rubber washer that will fit inside the cap and seal when tight.

You can wrap the bottle in plastic wrap(a few layers) and hit it lightly with a hair dryer to shrink it around the bottle.

Just some ideas for ya

As you posted this challenge at 11:51 on a Friday night, I'm surprised you didn't get some more creative, alcohol enhanced suggestions.

I know right?

I figured folks were off bashing beking's last few minutes on the board or partaking in more creative household activities

the teflon tape one? ??? that was a great suggestion

if that was alcohol induced perhaps we should increase the dosage and see what we get

If you use a bottle thats got a good amount of threads, use some teflon tape. wrap it around the threads and screw the lid on tight.No mess but just as effective as caulking would be. You really need to find a way to vacuume the air out of the sealed container though.Good luck it the project.

Guy's I think Litroy's hit the nail on the head.

 

[StromBusa]

Find a candle that just fits, let it burn down some, enough to wax the seal tight.

 

[omslaw]

You could do two things...

1) teflon tape on the threads

2) fill the bottle 'til overflowing. Then while screwing the cap on, gently squeeze the bottle, forcing the contents (and air) out. When the cap is tight, there will be no air in the bottle.
