TL;DR: A detailed study of the failure of an underwater column of magic sand shows that these properties can be traced to a single phenomenon: the system self-generates a cohesive skin that encapsulates the material inside.
Abstract: Magic sand, a hydrophobic toy granular material, is widely used in popular science instructions because of its nonintuitive mechanical properties. A detailed study of the failure of an underwater column of magic sand shows that these properties can be traced to a single phenomenon: the system self-generates a cohesive skin that encapsulates the material inside. The skin, consisting of pinned air-water-grain interfaces, shows multiscale mechanical properties: they range from contact-line dynamics in the intragrain roughness scale, to plastic flow at the grain scale, all the way to sample-scale mechanical responses. With decreasing rigidity of the skin, the failure mode transforms from brittle to ductile (both of which are collective in nature) to a complete disintegration at the single-grain scale.

TL;DR: In this article, the overhead projector offers an interesting way to demonstrate the properties of magic sand, and several demonstrations are described that compare the properties between hydrophobic magic sand and hydrophilic regular sand.
Abstract: The overhead projector offers an interesting way to demonstrate the properties of magic sand. Several demonstrations are described that compare the properties of hydrophobic magic sand and hydrophilic regular sand in water in separate petri dishes.

TL;DR: In this article, a super-hydrophobic waterproof roll has been proposed, which is characterized by isolation paper, first-layer self-adhesive rubber asphalt, the tire base cloth, second-layer Self-Adhesive Rubber asphalt and magic sand, and all the layers are made in high-temperature rolling and bonding manners.
Abstract: The invention discloses a waterproof building material. The waterproof building material comprises isolation paper and tire base cloth, and is characterized in that the isolation paper, first-layer self-adhesive rubber asphalt, the tire base cloth, second-layer self-adhesive rubber asphalt and magic sand are sequentially arranged from bottom to top, and all the layers are integrally made in high-temperature rolling and bonding manners. The super-hydrophobic waterproof roll has the following beneficial effects: a self-hydrophobic function is achieved, the probability of falling of fine sand is low after use, and the service life of the roll is prolonged.
