The SMS messages received from Fluid contain security codes, but it's unclear what service or product they are related to without further information. A quick web search reveals various definitions of the word "fluid," including its use in physics as substances that continuously deform under applied shear stress. Additionally, there are educational resources available online about fluids' properties and behaviors such as Bernoulli's equation derivation part 2, viscosity and Poiseuille flow among others on Khan Academy website which could be helpful for students studying science subjects like Physics etcetera..
