some famous reptile products are just simple things put together and sold for a ridiculous price. all it takes is just a little creativity and elbowgrease. so, lets get started... you will need: 1 gallon of purified water 1 siphon hose (that is typically used for fish tanks) 1 Nozzle a hot glue gun cut a hole in the bottom of the gallon of water and place the siphon hose in the hole and glue it together. make sure to use a lot of glue to ensure that there are no leaks. seal up the other end of the hose. poke some very small holes in the hose. place it on top of your cage and watch your new waterfall in action! it should only cost about $5.
