Question on helium regarding inflation
Just out of curiosity, does anyone know whether inflating a tyre with helium would make any difference on the over all performace or if it is even possible. I would think helium is not 'light enough' to warrant any difference in weight etc. Yet the child-like logic that has been bestowed in me by picture books and cartoons lead me to express my curiousity -- tobbogonist 'Corn Cam' (http://www.iowafarmertoday.com/corn_cam/) Yelling: 'Where's me faber castels?' monkeyman wrote: It's fun to run around, pumping a shotgun, and shooting at your friends.

Question on helium regarding inflation
There isn't enough volume in a uni tire to make any significant difference in its weight. Also, Helium atoms are the second smallest--and are likely to speed their way through the sides of the tube and tire during the course of your ride. -- lukkyjay john_childs wrote: Beer brewed with some marijuana will get you high hops. ~''~ unicycle for 'Flying Spaghetti Monster' (http://www.venganza.org/) ~''~ ------------------------------------------------------------------------ lukkyjay's Profile: http://www.unicyclist.com/profile/13562 View this thread: http://www.unicyclist.com/thread/56789 |

Question on helium regarding inflation
I think this was discussed a couple of years ago. My opinion - a tire would not hold enough volume of helium to make any significant difference in weight. -- Wheel Rider A man can fail many times but he isn't a failure until he begins to blame someone else. - Waite Phillips ------------------------------------------------------------------------ Wheel Rider's Profile: http://www.unicyclist.com/profile/10656 View this thread: http://www.unicyclist.com/thread/56789 |

Helium is very good at finding its way out of things - this is why (I think) helium balloons are usually all metal coated. If they're just rubber, the helium leaks out *through* the rubber really quickly. -- mark williamson Dave: Just a question. What use is a unicyle with no seat? And no pedals!

Question on helium regarding inflation
Whilst this is somethings of a stab in the dark I'm thinking that as the helium atoms are less dense and therefore further apart the tyre may compress more when you hop/ride/whatever so more prone to hitting the rim. Probably not enough volume to make a difference but you never know. -- twerpy ------------------------------------------------------------------------ twerpy's Profile: http://www.unicyclist.com/profile/13262 View this thread: http://www.unicyclist.com/thread/56789 |

If they're just rubber, the helium leaks out *through* the rubber really quickly. Another not-particularly-scientific response: while the idea of helium being small and likely to leak makes sense, my experience with rubber party balloons is that either helium or air will leak through, and I've not noticed a significant difference in time between them. As is seeming quite agreed, the 'lift' gained would not be of a useful or even detectable amount. Think how much a helium balloon can lift from the ground? Only a few tens of grams per balloon. I once spent hours at home after going to a fair trying to create equilibrium with a balloon, and all it needed was a small paper 'basket' with some extra paper in to fine-tune the weight. Those wacky types who go flying with balloons tied to a chair have thousands of them!
