It measures 11cm across the dome and is about 20cm tall.
You will need:
-Glue Sticks and Hot Glue Gun
An Old Pen
-Fibrous strands of plastic (Fibre Optics)
-Soldering Iron and Soldering Wire
-Deodorant Can Top/Cap
-Wire Cutters/Wire Strippers
-A Clear Plastic 2L Soft Drink Bottle
Step 1: Make the Shell
Optional: When done with this, sand the top of the dome with fine sandpaper as this will give it a blurry effect.
Step 2: Insert LEDs
Glue an LED into this gap and bend the prongs towards the centre.
Next, add a lump of glue on the opposite side in the dome and glue another LED on top of it. do the same procedure with the prongs as the first LED. This LED should face downward toward the centre.
Solder wires to the prongs accordingly, you will need 4 wires, about 23cm long.
Step 3: Attatch Part of the Stand
Also shown in this step, add bubble wrap to the outside of the dome and tape or glue the overlapping bits inside the dome. You only need to use 1 layer,with the bubbles facing inward.
Step 4: Make the Stingers
Once done with this, use your soldering iron to warp, bend, distort and shorten most of the stingers. Just touch the ends of them with the soldering iron and the tip will melt into a small ball. This makes all the difference to how realistic the complete jellyfish looks.
For 5 thicker stingers placed further out, twist about 8 fibres together and heat until they retain this shape. Do the same thing to the tips as before. Inthe last pic, you'll see I just used some hot glue to disguise the central support as a part of the jellyfish.
Step 5: Attatch Stingers
For the thicker ones, also just glue them in. Do this a bit further out though.
I also had some longer fibres, so I glued 5 of these to the outer edge of the dome for some added realism.
Step 6: Stand, Wiring and Completion
To complete the wiring, connect thewires to the batteries and add in a switch. I had to use 2 switches because the 2 LEDs refused to work in the same circuit. I glued some small watch cells together for the batteries because nothing else I had worked.
Your LED Jellyfish is now Complete!
