Okay, now I’ve been siliconing for about 4 months now and I think I’ive just about perfected it.Well for some of you who are newer here you may ask"what is siliconing a yoyo?", well different yoyos have different responses.Some have starbust, this is were there is a little thing that looks like a star bursting, thus the name star bust.This helps the yoyo come back to your hand when you tug it.
Here is a picture that you can see the grooves easily.http://i809.photobucket.com/albums/zz12/yoyolunatic/starbusrt.jpg
There is also silicone.This can be found at a local hardware store such as Ace or Home Depot.It is about 5-6 dollars per tube depending on the size.This allows the yoyo to be unresponsive(this means the the yoyo wont return to your hand with a tug you will have to do a bind return)(here is a link to a bind return http://yoyoexpert.com/learn/030-intermediate-bind-returns.html). Okay so back on topic.Silicone allows the yoyo to be unresponsive for more advanced play.People mainly use red rtv silicone.This is the best viscosity for what we need it for.So here are some tutorials on how to silicone
