Poke a hole in both ends of an egg with the toothpick. Wiggle the toothpick around to make the hole slightly larger and break up the yolk inside. Use the straw to blow against one hole to push out the egg yolk. Rinse out the egg and repeat with remaining eggs. Make a couple extra eggs in case one cracks along the way.
a tablet of blue or pink egg dye in a tablespoon of white vinegar in a large glass or metal bowl. Fill the rest of the bowl with water until there is enough water to completely cover the eggs. Put on latex gloves, then add the eggs one at a time, holding them completely submerged until they fill with the dyed water and rest at the bottom of the bowl. Let eggs soak until they reach a nice shade of color- the inside will be about the same or slightly darker as the outside.
Rinse out the eggs and let dry on a paper towel overnight. You may want to use a hairdryer to ensure there is no moisture left inside the egg. You can crack one of the extra eggs to check the moisture level and dye color.
Spraypaint the eggs white in several light coats. It’s helpful to use the “drying rack” from the Paas egg dye to keep them in place while painting, just flip the egg after each coat. Let the eggs dry completely.
Cut a piece of paper to 4” x ½” and write “It’s a boy!” or “It’s a girl!”. Roll up the paper into a tight scroll and push into one of the egg holes. Add several pinches of confetti into the egg.
Cut the white tissue paper into small circles slightly larger than the holes in the egg. Glue the paper circles over the holes in each egg. Assemble the paper boxes and fill part way with shredded paper.
Draw the labels. Cut out each label. Center the “Crack Me Open” labels on the inside of the box cover. Draw a question mark on each egg using the aqua paint marker and place an egg in each box. Close the box lids and seal with a strip of washi tape. Place a “What Will Baby Be?” label over the end of the washi tape. Mail this little surprise to close family and friends!
