Dear Alto, Soprano, Castrato and inhalers of Helium !!


Balloons are my all time favourite multi coloured inflated balls of rubber fun and joy !!

Look..here's some !!

[attachment=3217]


Ewe luff em, I luff em...we all luff em !!

LOL...balloons are just plain fun and often I just blow a load up for the kids to enjoy...and they brighten the place up too...

What I want to know though, is why do Helium balloons eventually lose their bouyancy ?...they're still inflated but don't float anymore *le sigh*

Why's that then ?



Thanks

Hugs and shmishes

They sink because eventually the helium seeps out of the balloon and then the air has been displaced causing the balloon to now be heavier and sink.

I also read that that the rubber balloon will deflate faster because the thin rubber is not an ideal container or as the article said barrier for the helium and that Mylar balloons last longer because of the mere structure of the mylar it holds better.

Beautiful Piccy Neil!

Rubber is a bit like a wicker basket where Helium atoms are concerned.

H and He are quite small molecules and seep out easily through the rubber, unlike CO2 which will keep a ballon filled for ages. It doesn't float very well though.

When things are in 3D, is it always the same three dimensions?

Thanks Karen....so it's not a case of the Helium losing it's ' lighter than air ' capability ?..it really is a case of seepage !..

Thank ewe.

Thanks Sophiecentaur.

So, Helium atoms are the Harry Houdini in the atomic world.....presumably because they are itsy bitsy teeny weeny !!

Thank You Turnipsock   I appreciate your corroboration of the above. This is great. I know something I did not know before. This makes me  appear extra klevur when the brats kids ask me about it ! [;)]

The song is called 'Heartbeat' and it's from the 'Veneer' CD/Album by a Swede named Jose Gonzalez.
...And its claws are as big as cups, and for some reason it's got a tremendous fear of stamps! And Mrs Doyle was telling me it's got magnets on its tail, so if you're made out of metal it can attach itself to you! And instead of a mouth it's got four arses!
