If you want a really wacky way to decorate the eggs, spin them in a bowl on a lazy susan (sold at many 100 yen stores.)
Here are some tips:
1. Put a small bowl on the edge, not center of the lazy susan, or the egg won’t roll
2. Put a damp paper towel under the bowl if it slides
3; Drip 2 colors of strong dye on the ends of the egg because they seem to remain white if you put the drips in the middle of the egg. Use a straw dipped in the strong dye, then put your finger over the opposite end, and release your finger once it is over the egg. DO NOT tip the straw, or the dye can dribble out before you are ready.
4. Cover the bowl with plastic wrap to guard against splatters and runaway eggs
5. Spin the lazy susan back and forth rather than around and around to get the egg spinning, and the dye spattering
