This little bowl (or big, that depends on what you need) is made from an empty roll of ductape and some ductape offcourse.
Its very simple and can have many uses, plus it is disposable (but can also be re-used in some cases) and it takes less than 5 minutes to create.

Necessities:

Empty ductape roll (or whatever shape you would like)
Ductape
Less than 5 minutes.

Step 1:

First cut or tear some strips of ductape in a bit longer length than the diameter of your to be bowl,
I made at least 5 strips 4 of wich are of the previous mentioned length and for the last one i used the end of the ductape (when the roll runs out) as a decal to finish things off.

Step 2:

Now its time to stick the pieces in place.

Stick the first piece of ductape in your to be bowl surface, i made a nice round bowl so i curved the first piece down before sticking it in its place, after that you cross place the second piece on to the first ductape you just put in there, than repeat what you did in a different angle so you get all openings closed, for this i only needed 4 pieces.

Step 3:

Finishing.

Now have to make sure all ductape fits nice together so it will not leak if you put any fluid in it, after doing this you can (if pleased) make it some nicer to look at by putting on some decal. For this i used the last (end) strip of ductape i could get of my (all but that) empty ductape roll with a little spare to make sure i can get it ductaped around my bowl so it will look "nice".

This dis can be used for a lot of different things and in some cases can be re-used, if not then it can always be disposed off (depending on the substance used). I used it for glue in wich case i can use it a couple of times before throwing it away.
