The present application is a § 371 National Phase Entry of PCT Application No. PCT/CA2019/0000031, filed Jan. 14, 2019, claiming the benefit of priority of Canadian Patent Application No. 3004436, filed May 9, 2018, now issued Canadian Patent No. 3004436, the entireties and content of which are incorporated by reference in to this application.
The embodiments herein particularly relate to light wand that produces light through bioluminescence. The embodiments herein also relate to a light wand comprising an agar-based casing with a pair of capsules therein that result in bioluminescence upon hydrating, and later, dissolution of the agar-based casing.
Glow Sticks are sold at many events, such as music festivals. It is estimated that 100 million of these glow sticks are sold a year, all of which end up in the garbage, creating unnecessary waste. Further, these festivals impact directly on the festival environment, not just through garbage being left at the site, but through damage to the turf.
An example of a glow stick is disclosed U.S. Pat. No. 3,774,022. The invention relates to a packaged luminescent material, and more particularly to a combined package of a chemiluminescent agent as the “fuel,” and an activating agent therefore, wherein the fuel and activating agent are maintained in close association but separated from each other by a barrier medium to prevent interaction before the same is desired. When the barrier medium is ruptured, or otherwise broken down, either deliberately or unintentionally, a reaction occurs between the chemiluminescent agent and the activating agent with the emission of visible light, without, however, the generation of any appreciable amount of heat. It is recommended that the outer material be glass or a plastic such as polyethylene, ethyl cellulose, vinylidene chloride. The material used is to be impermeable to water, moisture vapor and air. The chemicals used in the light wand and the outer material in which the chemicals are held are all non-biodegradable and are not recyclable. They create garbage at the site if they are dropped.
Biodegradable containers have been known for many years. An example of a biodegradable container is disclosed in U.S. Pat. No. 5,180,765, which discloses environmentally biodegradable compositions of poly(lactic acid) plasticized with lactic acid, D-lactide, L-lactide, meso D, L-lactide, racemic D, L-lactide, oligomers of lactic acid, oligomers of lactide, derivatives of oligomers of lactic acid, or various mixtures thereof; the compositions are suitable replacements of thermoplastic polymer compositions; the compositions are useful for pliable films and other packaging applications conventionally served by polyethylene and other nondegradable thermoplastics; homopolymers or copolymers of D-lactic acid, L-lactic acid, D-lactide, L-lactide, meso D, L-lactide, and/or racemic D, L-lactide having properties similar to other known polymers may be prepared by varying the ratios of monomer and polymerization conditions, the amount and type of plasticizer in the polymer and process conditions; additives and subsequent treatment are also used to modify properties. While these containers are biodegradable, they do not degrade quickly.
More recently, United States Patent Application 20160324207 discloses an edible material that may be made of liquid, sugar, and one or more hydrocolloids. The edible material may be used to form edible cups, containers, and the like and may be capable of holding hot or cold liquids for extended periods of time and have an extended shelf life. The composition forming the edible material may further be suitable for 3D printing 3D edible applications.
Bioluminescence has been used as a research tool and more recently, in novelty items. U.S. Pat. No. 6,436,682 discloses isolated and purified nucleic acid molecules that encode a luciferase from Renilla mulleri, Gaussia and Pleuromamma, and the proteins encoded thereby are provided. Isolated and purified nucleic acids encoding green fluorescent proteins from the genus Renilla and Ptilosarcus, and the green fluorescent proteins encoded thereby are also provided. Compositions and combinations comprising the green fluorescent proteins and/or the luciferase are further provided. These are used in diagnostics, high throughput screening and novelty items.

Natural hydrocolloid—in the context of the present technology, a natural hydrocolloid one that is derived from living organisms and is a substance that can gel when combined with water and is defined as a type of mechanical mixture where one substance is dispersed evenly throughout a water-containing liquid. Many hydrocolloids can change their physical behavior and characteristics with the addition or elimination of heat and have the ability to thicken and form gels at low concentrations. Hydrocolloids are generally polysaccharides (complex sugars), and when dissolved in water, forms a layer of water with restricted movement as a result of the water being attracted to the sugar molecules. This restriction of water movement gives hydrocolloids their ability to gel. Different hydrocolloids have different physical properties and different chemical properties such as molecular size, charge, and the distribution and composition of different side chains along the main sugar chain. These differences result in different gelling behaviors. Types of natural hydrocolloids include agar, pectin, carrageenan, gelatin, corn starch, gellan gum, guar gum, gum arabic, isomalt, konjac, lecithin, locust bean gum, maltodextrin, methylcellulose, sodium alginate, xanthan gum, and tapioca. The preferred hydrocolloid is agar.
Natural syrup—in the context of the present technology, a natural syrup is plant-derived and has a dynamic viscosity above 1000 cps at room temperature. According to certain embodiments, the syrup has a dynamic viscosity above 100 cps at room temperature.

According to one embodiment herein, in use, a user removes the cap of the light wand and pours water or other suitable fluid, for example a buffer, or a fluid that includes at least one plant-based pigment into the bore, as needed. In the alternative embodiment, the user shakes the light wand until the water-proof shell is broken. The user then recaps the light wand as needed and gently agitates the fluids to allow for dissolution of the tablets. The bioluminescence is emitted through the tube. The color of the light will depend upon the color of the pigment in the tube and/or in the fluid, if there is any pigment added to the tube or the fluid. Once the bioluminescence is expended, the tube continues to absorb the fluid, becoming distended and distorted. The user may remove the cap if it is metal, or, if it is a second bio-plug, may leave the light wand intact. The bio-plug absorbs the fluid and the mycelium begin to grow and the seeds begin to germinate.
