Unleash the world of creativity with Tuban Galaxy Slime DIY XL STEM Kit. Enjoy creating a slime that looks like a sky galaxy with this kit. The set features black PVA glue, an activator, and neon-glitter accessories. Pour the PVA glue into a container, add the glitter accessories to it, and mix it thoroughly. Now, pour the activator slowly into the shiny mass and stir the mass until it begins to separate from the container wall. Knead the slime till it reaches the perfect consistency. Add more activator if it still sticks to your hands. The slime will retain its properties for a long time and will not dry out if you store it inside a container.
