Description

[Technical field]

[0001] To provide an experiment kit for dry liquid, liquid marble, etc., which allows even children to safely and easily create dry liquid or liquid marbles and further allows experiments to be carried out utilizing the properties of fine powder. [Background technology]

[0002] Conventionally, dry liquids and liquid marbles, in which aqueous components are coated with fine powder that has been hydrophobic or hydrophobized, have been used as powdered cosmetics.

[0003] Furthermore, in recent years, dry water has been attracting attention as a material that can easily capture and store greenhouse gases such as carbon dioxide, methane, and nitrous oxide, and scientific experiment events to create dry liquids such as dry water have become more common.

[0004] Dry liquids can be easily made by mixing an aqueous component with a few percent by weight of hydrophobic or hydrophobic treated fine powder relative to the aqueous component, so at science experiment events and the like, it is common to make dry liquids by measuring specified amounts of fine powder such as hydrophobic fumed silica and liquid such as water, and mixing them in a mixer or the like (Non-Patent Document 1, Non-Patent Document 2).

[0005] In experiments like the one above, it is common to use 10 to 100 ml of water, and therefore it is necessary to measure out a fraction of a gram to several grams of hydrophobic fumed silica, etc. To do this, a hooded electronic balance is used to avoid the effects of wind from air conditioners, etc.

[0006] In addition, fumed silica, which is in the form of a fine powder ranging in size from a few nm to a few microns, has a very small weight and therefore easily scatters when weighing, etc., resulting in the waste of expensive fumed silica and the experimenter or observer inhaling fumed silica that has been dispersed into the air. As a result, accidents during scientific experiments have been increasing in recent years in elementary and junior high schools, and extreme caution is required.

[0007] Fumed silica has not been identified as toxic, but as a measure to prevent exposure and protect oneself, if dust is generated, one should wear a dust mask with a particle collection efficiency of 95% or more (Non-Patent Document 3). [Prior art documents] [Patent documents]

[0008] [Non-Patent Document 1] Masaya Miyake and Mitsuru Sato, Journal of Polymer Science, Vol. 72, No. 10, pp. 617-623 (Oct., 2015) [Non-Patent Document 2] Ryo Murakami Science and Education Vol. 66, No. 8 (2018) pp. 398-401 [Non-Patent Document 3] Ministry of Internal Affairs and Communications Nanomaterial Information Sheet Material name Silica produced by a dry method called flame hydrolysis or combustion hydrolysis As of June 2022 Summary of the Invention [Problem to be solved by the invention]

[0009] When measuring out such fine powders in amounts ranging from a fraction of a gram to several grams, a hooded electronic balance is used to minimize the effects of wind, but hooded electronic balances are expensive, and it is not practical to have multiple hooded electronic balances at elementary and junior high schools, science experiment events, etc.

[0010] Furthermore, when trying to weigh fine powder using an electronic balance as described above, there is the problem that, because fine powder is very light, considerable care and skill are required to weigh it reliably without scattering the fine powder.

[0011] In addition, when measuring fine powders such as fumed silica, or when transferring light-weight fine powders to a mixer, it is easy to imagine that the fine powder may scatter and be inhaled by experimenters. [Means for solving the problem]

[0012] The present invention provides a hydrophobic or hydrophobic treated fine powder, such as hydrophobic fumed silica, which is packaged (1) in easy-to-calculate amounts, such as 0.1 g, 0.5 g, or 1 g, which is convenient for each trial. The fine powders may be packaged in one or more packages of the same type, or in a package of different types, each package being one or more packages.

[0013] The containers, such as bags, into which the fine powder is individually packed are desirably made of materials that have been subjected to antistatic treatment. In addition, for example, the container such as the bag is preferably provided with a zipper (2) or the like so that the fine powder does not easily spill out. It should be noted that the above-mentioned treatment is not necessarily required for containers such as bags.

[0014] In addition, as an exposure prevention and protection measure, a dust mask (3) with a particle collection efficiency of 95% or more, such as an N95 protective mask or a DS2 dust mask, is provided.

[0015] Additionally, protective gloves (4) made of rubber, leather, or other materials may be provided as hand protection. Effect of the Invention

[0016] In the present invention, the fine powder is packaged in amounts that are easy to calculate, such as 0.1 g, 0.5 g, or 1 g, and are easy to use for each trial, so there is no need to use a hooded electronic balance or the like when preparing the amount of fine powder required for an experiment. This eliminates the need to prepare an expensive electronic balance, and also eliminates the need for the skill required to measure powder with an electronic balance.

[0017] In addition, by eliminating the need to weigh extremely lightweight fine powders, it is possible to minimize the waste of resources caused by scattering during weighing and the generation of dust in the experimental environment.

[0018] The present invention has the effect of encouraging the wearing of protective equipment during experiments by providing a protective mask or dust mask or other dust mask (3) and even protective gloves (4), and it also makes it possible to minimize the occurrence of accidents during scientific experiments.

[0019] Furthermore, there is no need to prepare separate protective equipment during the preparation stage of an experiment that is necessary and appropriate for experiments using fine powders, which can minimize the occurrence of accidents during scientific experiments due to insufficient preparation or differences in awareness of safety.
