Every Mummy and Dead-y know that Halloween is a holiday that’s made for kids. Here are 10 at-home Halloween activities you can do with your kids to get into the spirit of the season. From making a bubbling witch’s brew or a puking pumpkin to spooky and tasty treats, baking soda is your secret ingredient to bring these activities to life! Mwahahaha!


1. How to Make a Spooky Lava Lamp

How to Make a Spooky Lava Lamp with Arm and Hammer Baking Soda

You can make a lava lamp any time of the year, but you can make it extra spooky for Halloween fun with the colors you choose or making it glow under a black light. Red gel food coloring will help your lamp look as if it contains drops of blood. Glow in the dark food coloring will create a fun effect for your black light bulb and other spooky décor. It’s easy to make again and again so you can try different combinations.


Ingredients & Supplies

  • 3 tablespoons of ARM & HAMMER™ Baking Soda
  • Vegetable oil
  • Vinegar
  • Food coloring of choice – try glow in the dark coloring for extra spooky fun
  • Clean large empty bottle
  • A smaller container – for more Halloween fun, try a round potion bottle
  • Spoon or some item to mix with




  1. Add 3 large tablespoons of baking soda to your large container. The larger the container, the easier it is to see the bubbles move around.
  2. Fill two-thirds of your container with the oil. Do not try to mix the oil in with the baking soda.
  3. Portion out enough vinegar to fill the last third of your large container and pour it to a smaller cup or container. Then, add three drops of your chosen food coloring.
  4. Slowly add the vinegar and food coloring mix to the large container and your lava lamp will bubble up and spring to action! The vinegar reacts with the baking soda to create carbon dioxide bubbles that float through the oil.
  5. Place it on the table with a UV black light nearby and marvel at your mad scientist creation!
  6. A smaller container – for more Halloween fun, try a round potion bottle.
  7. Spoon or some item to mix with.


2. Release Your Inner Ghostbuster by Making Glow-in-the-Dark Slime

“Who ya gonna call?” might be a Ghostbusters phrase at Halloween, but you don’t need to be a paranormal scientist to help your child get slimy. With ARM & HAMMER™ Baking Soda, you can create glow-in-the-dark slime that provides awesome and otherworldly fun for you and your child! Just hit the lights and let the oozing begin with this ectoplasmic slime.

  • Beads, nonadhesive gemstones and glitter (glow-in-the-dark optional)
  • Saline contact solution



  1. Pour all 12 oz. of glue into storage container.
  2. Add the 1 ½ tablespoons of baking soda to the container and stir.
  3. If you’re using it, add a few drops of the washable glitter paint until it turns the desired color.
  4. Add 2 tablespoons of saline contact solution. You can add more and eyeball when the slime gets the right consistency.
  5. Add beads, nonadhesive gemstones and glitter.
  6. Place your substance in “indirect” sunlight so you can maximize the glow. Try turning off all the lights after you have “charged” your slime!
