This was the last workshop of the year and it was a fun one! We made a jellyfish and put it into a bottle, so we can take the ocean with us where ever we go!
- a transparent or translucent plastic bag (We noticed some bags work better than others, if they are too thin, the jelly doesn’t float as well. Some types of plastics have a lot of static and bubbles stick to it. You may have to experiment a bit)
- a transparent bottle with a wide mouth (the longer the bottle, the better the jelly ‘swims’ to the top)
- food coloring
Keeping the head at the top, spread out the bag and then cut from the corner to the neck. You should have 4 ‘triangles.’ Cut cut from the edges to the neck to make 8 ‘triangles.’ Cut off every other triangle, you should have 4 triangles.
You should make about 3 or 4 legs per segment, which means that you will still have to cut away some more of the excess bag. Trim the tentacles so they will be of different lengths.
Fill the bottle about 1/2 way with water.Fill the head part way with water (you will need to leave some room for air so the jellyfish will float up). Carefully insert the jelly into the bottle and top the bottle off with water. **
Turn your bottle upside down over and over again and watch your jellyfish float to the top. It’s absolutely mesmerize.
We found this great craft on BhoomPlay on how to make a jellyfish in a bottle.
* If you’re jellyfish is not floating to the top too well, try pulling him (or her) out of the bottle and blow a little bit of air into the head. If you have a lot of air, the jellyfish will float to the top quickly. If you have too little or no air, the jellyfish will float slowly or not at all. If you find a the right ratio of air to water, you jelly will float and will full everyone into thinking he (or she) is real!
