Bubble Hourglass Timer w/Blue Bubbling Liquid
25 Second Bubble Hourglass Timer
An interesting twist on the typical sand timer, this particular hourglass features a light blue liquid rather than sand. As it drips steadily from one bulb to the other, it leaves behind a cluster of bubbles. At approximately 6.5" in height with a bulb diameter of 2.5", it takes the bubble hourglass a total of approximately 25 seconds to empty its liquid contents from the top to the bottom. If allowed to rest with the bubbles at the top, they will eventually disappear until the next time the hourglass is flipped over.
