, this shows how you can turn a sheet of plastic in some kind of tube.

,

Step 1: Material and Tools:

,

, any kind of flexible plastic works. to demonstrate the technique i pulled a milk-bottle out of the trash.

tools:

__ anything to cut the plastic with (here a pocket-knife)

__ a source of heat and an object to transfer the heat with (here: a soldering-iron.... but if you are out in the wild etc: a campfire and some metal-object like a nail, fork, wire, kinfe etc etc works too),

,

Step 2: Gut (get) Some Plastic:

,

,here i cut out the even ´belly´ of a no.2 plastic bottle,

,

Step 3: Unbottled:

,

,for mere demonstration i keep it simple: this piece will do. (but, obviously, you can use any size of plastic, from any source, as long as you can bend it easily... see next step:),

,

Step 4: Roll It Up:

,

,whatever diameter you wish: roll the sheet up into

(the more layers/windings you got the better for the next step:),

,

Step 5: Weld It:

,

,carefully trace a soldering-iron lenght-wise along the tube.

you wanna burn in a seam without actually cutting through to the very inside, thus through, the tube. (see above: the more ´meat´ you got to h/eat into: the easier & stronger. example: lets say you have 6 windings in total, burn down to about the half)

if you do a clean weld/seam the resulting tube will be water-proof,

,

Step 6: Done

,

, i post this basic technique here because in future projects i will come back to it as a component. i like modular approaches.

if you have and questions or critique etc: more than welcome.

thank you all.
