To use MrBeast Lab Swarms, simply take a test tube from the 12 - pack assortment. Pour some water into it, then give it a really good shake. You'll see the Swarms come out from the fizz. Make sure to handle the test tubes carefully so they don't break. After you've created your Swarms, keep them in a dry and safe place. Don't expose them to extreme heat or cold. If you want to show them off, you can display them on a shelf. This product is for kids aged 5 and up, so adult supervision is recommended for younger kids.
