i'm making a science fair project and its on Ferrofluid (or a liquid like magnet) and i'm trying to create a generator by placing the liquid in plastic tubing. but the problem (obviously) is that is i don't seal the two open ends of the tube the liquid will drain out. what can i use to block the tubing?Oh almost forgot, my substance is a magnet so it can't be any material that can possibly conduct electricity.
Buy wood dowel the next size larger and cut a length and push it in. I would suggest E6000 or Goop rigid silicone adhesives, but check them on the plastic first.
i would probobly go with maybe a silicone based adhesive, caulking maybe? like what you use around bathtubs n such. it sets fairly quick, adheres to most materials and is waterproof. hope this helps.
You might also consider using Super Glue and pinching the ends closed with a pair of pliers until the glue sets.
