We were happy to discover that, once formed, the eggs would hold together while being scooted across the sand. That way, we could form them separately then group them together.
This has nothing to do with our sand sculptures, but we came across some interesting sea life this year. These Blue Buttons are not jellyfish, but rather they are colony organisms attached to a float, similar to Man O' Wars.
Finding these at the beach this year inspired me to design an origami Blue Button.
This video I took shows how they extend their tentacles in the sunlight then retract them while under the shade of my hand.
