Bubble fountain with means generating pulsating air - and diffusing odour of liq. by bursting of bubbles

摘要

Bubble fountain comprises a dish containing foamy fluorescent liq. and a transparent tube fitted telescopically onto a smaller dia. tube which is fixed to the bottom of the dish and at the lower end of which is a hole for inlet of foamy water. An air inlet tube extending through the smaller-dia. tube mixes the liq. forming bubbles which are expelled upwards through the transparent tube. Pref. a hollow base contains an air pump of which the output can be controlled by a button and may also contain a light source with external lamps for illuminating the bubbles during their ascent and descent. The column of descending foam may have regular or different shapes according to variation in the dish or accessories with different openings placed at the upper outlet of the transparent tube.
