this is sooo cool! and i got an idea too if you ever seen those 1 dollar draw liners the rubbery ones you could use those to open a draw or even put under a cutting board so you could add grip so it doesn't slip i haven't found other uses for it so far if anyone does please let me know this thing reminds me a little of the hamster toy i had from McDonald for goosebumps

What I usually do for a tough jar is get a belt and tighten it over a jar. That works much better then a towel, but this instructables helps me keep my pants off the floor. :P Awesome.
