There are LOTS of blog posts out there about how to make apple volcanoes, but if you haven’t done this with your kids, you really really should. It’s super fun to make the apple “explode.” Simply cut the core out, leaving the bottom in tact. Pour baking soda down inside the apple, and replace the core. Then, place it on a tray and pour vinegar over top! That simple! Becca enjoyed sticking her hands inside the “bubbles” and feeling the volcano. Then, she found the vinegar smell interesting, and enjoyed playing in the soap in the sink to help her hands smell better. All in all, it was a super fun after dinner activity!
