Latex balloons are porous, not a lot, but enough to let helium pass through.

Helium molecules leak slowly when there is barrier of Mylar Polymer and Aluminium in the way. Imagine Silver or Gold Metal Vacuumed into a sheet of Mylar Polymer.

Helium is inert and a single atom "looks" smaller than diatomic hydrogen (a molecule consisting of two hydrogen atoms usually found in nature). Latex rubber is composed of intertwined chains of polymer molecules that allow it to stretch until all molecules are pulled straight. Helium can fit throught the pores between the latex chains and leak. Mylar does not stretch as easily because the molecules are not a jumble of polymer chains like rubber.

Helium is a small atom and diffuses more easily than the substances in air. Mylar has very small pores compared to rubber balloons and the diffusion is reduced considerably as a result.

Helium molecules are smal enough to slowly leak through the latex. Mylar is truly airtight. Its that simple.

**recommend a artwork tension time out -- liquids, bowling, karaoke, something would be familiar **set up a furnish of frustration (may be a tech undertaking or a foul technique) and ask your boss if which you will scheduled a brainstorming assembly w/ the gang to communicate. in case you scientific care the unhappiness, morale will develop. **have relaxing birthdays on the workers with a balloon or cake **If any of your colleagues are being overly detrimental, try taking them out for coffee and enable them to vent. One detrimental guy or woman on the team can carry each and each guy or woman else down. in simple terms surprising luck!!
