What is ferrofluid? Matters needing attention Magnetic fluid is an environmentally friendly and non-toxic magnetic substance, mainly composed of a mixture of very small iron particles and surfactants in base oil. This liquid substance, due to the fact that surfactants do not precipitate and can be uniformly dispersed in base oil，was first developed by NASA in the ����s for fuel transportation and sealing connections in spacecraft, Science fiction elements that once existed only in space have now become widely used magnetic materials in the real world. ·Do not use continuously for more than �� hours (at least � hour of ooling time is required) ·Only for indoor use, reducing sunlight exposure. The optimal operating environment temperature is ��-�� °C. ·The more intense the motion of magnetic fluid, the shorter their lifespan ·Do not connect the external magnet to the glass bottle for an extended period oftime to prevent magnetic fluid from sticking to the bottle wall ·Reserve bubbles inside the magnetic fluid bottle to prevent thermal expansion and rupture of the glass bottle ·Please do not remove the contents of the glass bottle and touch or consume it with your hands ·Do not place in high or low temperature environments to avoid the rupture of the magnetic fluid bottle body, such as in a closed car or outdoors in winter ·lf the contents of the glass bottle accidentally touch your hands or enter your eyes, rinse immediately with running water. Soap or hand sanitizeir can be used to clean hands. After rinsing with eye water, seek medical attention immediately ·Magnetic fluid layering: Remove the magnet and suck the magnetic fluid back into a whole to observe whether there are bubbles wrapped inside. After the bubbles are expelled, continue to use for better visual effects ·Magnetic fluid contamination bottle? If the magnetic fluid is left at the same angle for a long time without use, there may be bottle sticking due to temperature differences. The bottle can be removed from the product and the position of the bottle sticking can be sucked by a magnet to allow the magnetic fluid to aggregate Baobu Magnetic fluid Bluetooth Speaker Product accessories Product accessories: Magnetic fluid audio body, instruction manual, power adapter, small magnetic handle.
