The word paludarium comes from the Latin word ‘palus’ meaning marsh or swamp and ‘–arium’ meaning enclosed container. How many species did you find in the Paludarium in the museum lobby? Did you see the big angelfish? Were you lucky enough to catch a glimpse of a crab hiding in the moss on the rocks? The Paludarium is a living ecosystem where all of the living elements (mosses, plants, crabs, and fish) and non-living elements (the water, air, and rocks) interact with one another and are linked through nutrient cycles and energy flows. The balance of the ecosystem is supported each day with just a little food for the fish.
Fossils are clues that tell the stories of plants
and animals that lived millions of years ago.
Paleontology is the study of fossils and
seeks to map out how life evolved over
geologic time. Using clues from biology,
biochemistry, geology, mathematics and
engineering, paleontologists construct ideas
of how animals looked, behaved, interacted
Step into the Fossil Dig, grab some
excavating tools and use the skills of a
paleontologists to unearth the unique stories
of these amazing creatures! How many
fossils can you find in the Fossil Dig?
Cell Phone Disco
Use your cell phone to transform an entire silo into a dazzling light show! Several thousand lights illuminate when you use a mobile phone in the vicinity of the exhibit.
Every single mobile phone transmits radio waves to connect to a cellular network, and every day millions of people around the world broadcast their conversations across these invisible waves. Tiny sensors in this exhibit detect and convert the invisible electromagnetic waves from a cell phone into another frequency, the range of visible light. Thousands of sensors incorporated in the display are tuned to detect the phone’s electromagnetic radiation.
African Spurred Tortoise
African Spurred Tortoises, native to the Sahara Desert, are unique reptiles known for digging extensive burrows in the ground to escape the heat. Their name comes from the enlarged, pointed scales on the hind limbs. These animals can reach over 200 pounds in size and can live up to 150 years! At the Science Mill, we have two Spurred Tortoises who live in an underground burrow. Speedy is an 11-year-old male weighing 60 pounds, and Tortilla is a nine-year-old, 40-pound female. Both tortoises enjoy lounging in their burrow, exploring their enclosed habitat and eating plants (they are herbivores). Stop by during our tortoise feeding hours at 2:15 on Wednesdays and Saturdays to help us give them leafy greens, fruits and veggies. If the tortoises are resting in their burrow, you can watch them on our 360-degree tortoise cam in the lobby. Don’t forget to bring your great-grandchildren back to see Speedy and Tortilla, who may still be going strong at 100 years old.
The Story of Water
Movement of underground water through big caves and tiny cracks and crevices in rocks is the often invisible part of the water cycle. In this exhibit, while in a 40-foot-tall silo, you will be immersed in an aquifer and experience the great cycle of water – from the air to the ground, deep into the earth and back into the sky.
Put mathematics, art, and biology together and you get this model based on Romanesco Broccoli. The broccoli takes the form of a fractal – a complex geometrical shape that looks the same at every scale factor. Though the exhibit has an infinitely increasing perimeter, you’ll be surprised to know that it has no area as the dimensions of each fractal become so small they advance into nonexistence! The unique structure of the Fractalarium will tempt your curiosity as it conveys the geometric rhythms of energy that harmonize the universe into pattern, life and consciousness. Looking at this masterpiece is quite literally looking at infinity!
Silo of McKays
Enjoy the peace and serenity within this silo created by Wimberley artist, McKay Otto. It serves as a multidimensional space for meditation, reflection and self discovery.

Connect, Spark, Flow--These are the names of each of the three panels comprising Realms, the digital holographic display created by Austin artist Sally Weber for the Science Mill. She thinks of matter as dense light, which is why finite points of light compose the objects in the panels. Solidity is displayed as translucent in this exhibit as light is manipulated. These images were created using a circular grid modeled from an astrolabe, the first instrument to map the dome of the heavens on a flat surface. Looking into each panel reveals an image that extends far beyond the frame, and infinity seems to fall away below the viewer’s feet!
