Unleash your inner scientist (or outer scientist, if you happen to be working in a lab) with this Teatube Test Tube Tea Infuser. The infuser looks very similar to a “real” test tube, but the glass has several vents cut into it that will allow hot water to flow into the tube and tea-infused water to flow out. The shape makes it perfect for stirring, so you can get a nice water flow going as you brew. It has a lovely wooden plug/handle – not quite like what you would find on a “real” test tube – that makes it easy to handle and stays cool even when the infuser is in hot water. The plug pops out to allow you to easily refill the infuser with tea and clean it out after use.
