I started with my students. I asked them if they thought baby was a boy or
girl. We planned on using their data at the reveal. I made sure to do this before the ultrasound so that I did not show any tell when they were guessing! They guessed girl!
Next was making the volcano! I made the volcano from an personal little milk. I chose this because the opening was bigger than a water bottle and shorter than the vase I was going to use.
I then made the "lava." I mixed one box of baking soda (I have to do this 3 times: 1 at the party, 1 for my AM 4k, and 1 for my PM 4k so I need quite a bit. Someone doing this once would need only 1 box.) I put 1/2 a bottle of food coloring in the baking soda and stirred it it until there were no dark clumps. I left in a ice cream container hidden in a closet in case someone visited to "dry out" over night.
I then made the volcano. I made a batch of salt dough:
1 cup salt
1 cup water
2 cups flour
and stirred until dough like. I the formed it around the milk bottle. I had some left over so I rolled it out to make letters "Boy or Girl?"
I left that to dry overnight as well.
The morning of the party, I put the lava in with a paper funnel and put the top back on the milk container. We are party ready!
