The goal is to be able to push on the edge of flowmass without squeezing the mass, as this causes the mass to tighten more. If you can find a piece of tube/pipe that just fits over your flowtoys tube, you can slip it over the flowtoys tube and push against the edge of the mass to get it out. Or you can use the edge of a table. 

If you cannot remove the mass, you can always send it in to us and we can do it for you. Feel free to contact us if you have any questions!
