My daughter has been asking for one of those nifty LED Jellyfish Aquariums advertised prominently on Saturday morning television. Browsing through for one, though, gave me sticker shock for a fake jellyfish. They start at about $30.00 and go way up from there. I’m not spending that kind of money on a toy she’ll lose interest in after two weeks.

So we headed to the kitchen for this fun DIY activity. In just a few minutes and with minimal supplies, we had our own jellyfish in a bottle! We saved a lot of cash and spent some fun time together.

You Need

  • A transparent plastic grocery bag (free)
  • A plastic water bottle or 2 liter soda bottle (free)
  • Thread or white dental floss
  • Food coloring (about $3.50 at Walmart)
  • Scissors

The Steps

  • Flatten the bag and snip off the handle and the bottom seam.
  • Cut along both sides to split the bag into two plastic sheets. Only one sheet is needed.
  • Make a tiny “balloon” head for the jellyfish with the center of the plastic sheet, and tie it loosely with the thread or floss. Leave a little hole for water.
  • Cut the “body” part of the jellyfish into shreds creating tentacles in the plastic. These can be all different lengths and widths.
  • Fill the bottle about 80 – 90 percent full with water, and add a few drops of blue food coloring. Shake well to mix.
  • Put a few drops of water in jellyfish’s head. Press the jellyfish into the bottle and let it sink.
  • Place the cap back on tightly.
  • Turn the bottle upside down and watch it swim and float to the surface!

Kids will have a blast creating this “aquarium” and watching the jellyfish swim. Best part? No fish food or stings! My child wanted to throw in some silk greenery we had to make her ocean even more realistic.
