say i meant to ask, what you use the surgical tubing for ? slingy shot or firetube (for forcing air into fire) 
You can also use it to suck or siphon water. 
If things are desperate, surgical tubing can be used as a tourniquet. 
I cut a length of copper tube with an OD that matches the ID of the surgical tubing. It slides in snug. That way I can blow air into a fire just where I want it, without melting the rubber tube.
