This geocache features one of the most popular things I use to entertain any new students I come in contact with. Everyone and I mean everyone smiles when they experience it. They usually act very surprised too. I made the discovery of this phenomenon serendipitously when experimenting with balloons many moons ago. At the geocache you'll get the opportunity to feel it for yourself!
The phenomenon occurs because our hands are one of the most touch sensitive areas on our bodies. According to this New York Times article, “The human finger is so sensitive it can detect a surface bump just one micron high. All our punctuation point need do, then, is poke above its glassy backdrop by 1/25,000th of an inch — the diameter of a bacterial cell — and our fastidious fingers can find it.” I don’t use the fingers but instead use the palms.
When you open this cache you’ll find (1) a locked match container that has the log in it, (2) a pen that writes on the Tyvek the log is made of, (3) a few balloons, (4) some marbles, and (5) a wire that aids in the extraction of what's in the geocache. Even though I don’t consider the balloons and marbles to be swag, you can take one or both if you don’t have either at home. Just make sure to leave at least one of each in the cache. Please be sure not to break anything when re-stuffing the cache.
Do not ask for a hint about the combination of the lock. This cache is rated difficult because you may have a bit of a time with it. Please do not create a log unless you actually sign the Tyvek!! Simply making an easy find is NOT enough.
