Fountains meanwhile are a very flexible form of water feature. These come in all shapes and sizes. Like water falls fountains can be large and be the main focus point of a room, or they can be a smaller side attraction, even placed just on a table or windowsill. Again though they are great for drawing attention to themselves because of the noise and the interactive aspect. Fountains often give the illusion of perpetual motion and this makes them very interesting to watch. Again at a tradeshow or industry fair this way you can attract over individuals who are curious about the fountain and then start talking to them about your business. This is particularly effective if your business in some way corresponds to water, energy or a related matter. Finally you can look into custom aquariums as water feature rentals. Here again you have the option of a great centrepiece for a room which will come with fish as well as the tank itself which will be glowing and refracting the light around it. The great thing about fish is that they`re alive making them interactive and entertaining. At the same time they are highly unusual and many of us have never seen the more peculiar varieties. Children in particular love custom aquariums.
