	Pressure and Thistle tubes
		In case you are wondering the thistle tube is the tube with a bulb-like opening at the top in the attachment.
		Clearly, if your thistle tube were not below the surface of the liquid in the beaker, any gas generated by your reaction would simply exit the beaker through the open tube to the atmosphere.
		With the Thistle tube below the surface of the acid, once the pressure in the beaker is greater then atmospheric, the gas will displace water in the collection beaker.

	BirdFeedersOnly.com \| Nyjer (Thistle) Bird Feeder Tube
		Nyjer, sometimes mistakenly called Thistle, is enjoyed by some wild birds due to its excellent nutritional value that includes high fat and protein content.
		On the contrary, Nyjer is not a thistle weed at all, however, some birds, including goldfinches, do eat seeds from the thistle plant.
		It should be noted that some bird seed mixes do include thistle in them, but because the other parts of the bird seed mix are generally large, these mixes require a more multi-purpose bird feeder.
