According to National Geographic, the venom of the box jellyfish (also called sea wasp, fire jelly or marine stinger) is considered to be among the most deadly in the world. A model of the fire jelly for a science project can be made from household and craft supplies to reflect the unique characteristics of the organism: 24 eyes, four sets of stinging tentacles that can grow to 15 feet and a boxy (cube-like) bell.
Dab a one-inch circle of glue in the centre of the square bottom of the tall, clear plastic container.
Carefully line the container with clear plastic, making sure it is long enough to extend at least one inch over the top edges of the container.
Place your food can in the lined container to weigh the plastic down as the glue bonds it to the bottom of the container.
Allow the glue to dry completely.
Divide the Velcro roll into 32 even segments by folding the entire length in half and cutting it and repeating until 32 pieces are obtained (each approx. two feet long).
Remove the food can from the container and glue four craft eyes to the bottom, clustered over the centre glue area.
Turn the container over (bottom side up), pull the extended plastic lining out and carefully tape the lining to the rim of the container to form a flexible skirt (velarium). The tape should be evenly placed to cover both the rim and the bag so that the velarium hangs down.
Glue four craft eyes in a cluster at the centre of each side of the container, approx. one inch from the top rim (i.e., above the velarium).
Glue a cluster of four eyes to the bottom (outside) of the container.
Separate the Velcro lengths, discard the smooth sides (loops) and divide the rough lengths (hooks) into four groups (eight lengths per group).
Organise each Velcro group so that the ends align and wrap four inches of tape around each group to secure (to form the pedalia and tentacles). Repeat with remaining three bundles of rough Velcro lengths.
Tape each wrapped bundle to the inside corner of the lined container and allow the pedalia and tentacles to hang down.
Use clear epoxy gel to glue the plastic liner to the plastic container. Arrange your Velcro bundles so that all rough sides are facing out.
Tips and warnings
- Use clear epoxy gel to glue the plastic liner to the plastic container.
