Glow-in-the-Dark Jellyfish

The Jellyfish is an incredible invertebrate that lives in the ocean! They have stinging tentacles that can stun or paralyse their prey before gobbling it up. Some of them are bioluminescent, which means that they produce their own light. That also means that they have the amazing ability to glow in the dark! 

ūüí° Get hands-on and create your own glow-in-the-dark jellyfish to brighten up your room!¬†

    What you need 

    1. Paper Bowls

    2. White Yarn

    3. Glow-in-the-dark Paint

    4. Paintbrushes

    5. Scissors

    6. Skewer

    7. Zip-lock Bag


    Step by Step

    1. Start off by painting your paper bowl using your paintbrushes and glow-in-the-dark paint. That would be the body of your jellyfish. 

    • You can choose to coat it with 2 or more layers of paint for a brighter glow!¬†

    2. Cut 10 to 12 strands of white yarn for your jellyfish's tentacles. 

    • Don't cut your tentacles too short! Each strand should be approximately 90cm for a brighter¬†effect when you hang it up.¬†¬†

    3. Put your white yarn in a zip-lock bag and squeeze some glow-in-the-dark paint in the bag. Seal it and squish it until your white yarn is completely covered!

    • If you would like your tentacles to be rainbow coloured, place 2 to 3 strands of white yarn in a zip-lock bag at each time and repeat the process with different coloured paint.¬†

    4. Hang the yarn and wait for it to dry. 

    5. Use the skewer to poke two holes about 3cm apart using your skewer (Please seek adult assistance for this step!). 

    6. Cut a longer pieces of yarn and thread it through the two holes before you tie up both ends. This will the handle and the loop for your to put your tentacles through. 

    7. From the inside of the bowl, pull the handle to form a small loop. Put your tentacles through and roughly center them in the middle. Tie a knot to secure the tentacles in place. 

    8. Are you ready to watch your jellyfish light up? Charge your jellyfish under the bright light for at least 30 minutes. Then, you can hang it up in a dark room and watch its luminous glow!
