I didn't used it but IIRC there are a couple of videos showing how to do that. The problem with mega-carts is that since they are longer (510 mega-carts) or wider (ego/tornado mega-carts), the plug is not properly holded in the top of the cart so you need to use some artifact to hold it such as a straw or a spring.

I'm still using this mod. I haven't even looked for another since trying it . My thanks to highping
ummm. for a newbie who is visual, can someone post a pic of this? are you saying you only have a small part on top and no filler by the mouth piece? how is the juice not going to end up in my mouth? i'd love to try this...
can you do this mod with the whistle tips for 510 or 901?
