In magnetic levitation, a strong and spatially varying magnetic field exerts an upward force on a body that is sufficient to counteract its weight due to gravity. Here we show that this effect can be enhanced by immersing the body in cold oxygen gas, which provides a further strong and adjustable buoyancy force that allows a wide range of materials to be levitated in an open, unpressurized vessel. The buoyancy of magnetized liquid oxygen is sufficient to float even gold and platinum, suggesting that this technique could find application in mineral separation. An interesting periodic pattern is created on the surface of this pure elemental paramagnetic fluid.
We also noted the formation of a regular pattern of peaks on the surface of slowly boiling liquid oxygen; this pattern is held as a membrane at the centre of the magnet bore (Fig. 1a, c, d). The peaks arise from a combination of magnetic and surface-energy effects and have been observed before in synthetic ferrofluids3, but their appearance in a pure elemental paramagnetic liquid merits further investigation.
At high magnetic-field strengths (B > 13 tesla), a simple square-lattice structure, decorated by edge dislocations, can be formed inside a small rectangular frame. In weaker fields, hexagonal close-packed crystallites are evident. When the heat input to the liquid oxygen is sufficiently great, the fluid exhibits convection and turbulence, which causes complicated motion of the microcrystallites and dislocations (see supplementary information). This could provide an experimental test bed for models of crystal formation and dynamics.
Welcome to floating, which can provide up to 100% pain relief. The spine naturally elongates and straightens, and the body undergoes the same regeneration process that transpires during sleep. Lactic acid is drained from the muscles, reducing soreness and recovery time.
Epsom Salts are great for your skin, hair, nails, and act as an exfoliate. They aid in joint pain, ease stress, and naturally relax the body. Magnesium (commonly missing from our diets) is absorbed through the skin, while Sulfate eliminates toxins and heavy metals, naturally detoxing the body.
Taking an hour of alone time (meditation), will decrease the production of cortisol, a stress hormone, leaving us feeling refreshed and serene after the float. The brain enters an elusive theta brain-wave state, associated with deep sleep and dreaming.
Clients experiencing chronic pain or who are recovering from an injury are encouraged to begin floating with a series of consecutive sessions, and transitioning into a Monthly Membership to maintain relief.
Last year, the Waterway Stewardship team received a grant from the The Green Initiative Fund (TGIF) for the design and installation of the floating island. This two quarter long, student-led process involved the meticulous planning and development of the floating island design, materials, and plant layout.
The island features attractive native plants such as the sedges and rushes you would see along nearby Putah Creek, as well as colorful flowering plants like purple aster, California native sunflower, and milkweed. The Waterway Stewards will swap out the plants every winter, before the plants die back and release the phosphate and nitrate nutrients back into the water. The tallest native plants, placed in the middle of the island, are expected to grow about four feet high. Check out the complete list of plants on the island here!
Simply put, a floating fountain is an electric motor attached to a float that physically forces water into the air. As water is propelled into the air, circulation occurs around the fountain, and the natural oxygenation of the water column is enhanced. Floating fountains come in different shapes, sizes, and spray patterns and can serve as the focal point of a pond while helping improve water quality. One thing to keep in mind is that the more appealing the display, either with a nozzle or special flow chamber, the less water is being circulated which can limit oxygen introduction.
Surface aerators are designed similarly to floating fountains but have the sole purpose of water movement and oxygen input. These systems run at lower speeds with large propellers that produce a boil-like flow on the surface of the water. Surface aerators are excellent for problematic ponds due to their ability to maintain a high flow and inject up to 3 lbs of oxygen per horsepower, per hour into the water. Ponds with less than 4 to 6 feet of average depth should consider either a floating fountain or surface aerator.
Submersed aeration can effectively increase DO levels in lakes and ponds with average depths above 4 to 6 feet. Submersed aeration systems have a compressor on shore that pumps air through tubing to diffusers located on the lake bottom that release fine air bubbles, creating a lifting action. These systems do not directly inject oxygen into the pond, but help circulate large amounts of water, which helps increase oxygen levels. These systems work better in deeper and larger waterbodies and are usually the best solution to break thermal and oxygen stratification.
There are many techniques to help increase dissolved oxygen levels, and aeration is a tried and true method. These solutions can be paired together to help introduce more oxygen to your waterbody. Whether you should combine these aeration solutions will depend on your goals for the waterbody.
Water quality issues, logistics, and your overall goals will dictate which system is the best fit for your lake or pond. It is recommended to work with a lake management professional to properly size, install, and maintain the aeration systems to ensure they function properly for years. Remember, lakes and ponds with aeration can still present water quality issues, so it is important to regularly monitor your water to stay ahead of issues, resulting in a beautiful pond all year round.

Lettuce (Lactuca sativa L., cv. Ostinata) growth experiments were carried out to study the effect of dissolved oxygen (DO) concentration on plant growth in a floating hydroponic system. Pure O2 and N2 gas were supplied to the hydroponic system for precise DO control. This system made it easy to increase the DO concentration beyond the maximum (or saturation) concentration possible when bubbling air into water. Eleven day old lettuce seedlings were grown for 24 days under various DO concentrations: sub-saturated, saturated, and super-saturated. There was no significant difference in fresh weight, shoot and root dry weights among the DO concentrations: 2.1 (25% of saturated at 24 degrees C), 4.2 (50%), 8.4 (saturated), and 16.8 (200%) mg/L. The critical DO concentration for vigorous lettuce growth was considered to be lower than 2.1 mg/L. Neither root damage nor delay of shoot growth was observed at any of the studied DO concentrations.
This plant is also on the Washington State quarantine list. It is prohibited to transport, buy, sell, offer for sale, or distribute plants or plant parts of quarantined species into or within the state of Washington or to sell, offer for sale, or distribute seed packets of seed, flower seed blends, or wildflower mixes of quarantined species into or within the state of Washington. Please see WAC 16-752 for more information on the quarantine list. For questions about the quarantine list, contact the Washington State Department of Agriculture's Plant Services Program at (360) 902-1874 or email PlantS...@agr.wa.gov.
It forms dense, fast-growing, floating mats that can displace native aquatic plants and wetland grasses. Mats can also lower dissolved oxygen and pH of the water, reduce water quality for wildlife and increase sedimentation.
It is an herbaceous, perennial wetland plant whose sprawling stems usually grow flat along mud or a water surface. Water primrose, Ludwigia hexapetala, a Class B noxious weed in Washington, looks very similar and they can be very difficult to tell apart.
Flowering stems are floating or lying on the ground. Flowers have five bright yellow petals, 0.4 to 0.6 inches (1 to 1.5 cm) long. The flowers occur on long stalks arising from the leaf axils (upper angle of where leaf attaches to stem).
They are alternately arranged, clustered and vary in shape and size. They can be lance-shaped to egg-shaped and are up to about 3.5 inches long. Leaf bases tapers to a stalk that ranges from 1-1.5 inches long. Leaves are hairless and have smooth margins.
Water primrose, Ludwigia hexapetala, a Class B noxious weed in Washington, looks very similar, and they can be very difficult to tell apart, even for experts. If you need help with identification, please contact your county noxious weed coordinator.
Floating water-primrose grows along freshwater shorelines and sprawls across the water's surface. It typically inhabits margins of lakes, ponds, ditches and streams. It can tolerate water depths up to around 10 feet. Please click here to see a county level distribution map of floating primrose-willow in Washington.
When removing floating primrose-willow, be sure to remove as many plant fragments and roots as possible. Be sure to dispose of plants properly. If you use a method that will kill the plant, keep in mind that the decomposing plant will cause a drop in the dissolved oxygen. Treating only a portion of the floating mat at a time, or removing dying plant tissue will help reduce this risk.
