in a project tornado with 2 plastic bottles, what can I use instead of a tornado tube?

I am in hollywood CA and I need a tornado tube, and I can not find it, what else can I use if I can not find that tube?

We always used wide electrical tape. Works fine. [EDIT] MacGuyver was a tv show from the 80s. This guy could do anything with whatever he found lying around. You should totally check it out.

Go to an electronics store and they should have something that could help.

You can always try to MacGyver it with some duct tape...
