Last May, my boys and I made a spouting blue whale in our backyard. It turned out really cool! Mixing baking soda and vinegar was the secret to our success. Since then, my boys have asked, on many occasions, to do the activity again.
This time we challenged ourselves to come up with a ghost-themed baking soda and vinegar experiment. We came up with the idea of a ghost blasting out of a grave!
2. Cardboard box
3. Paint and paintbrushes
4. Plastic water bottle
5. White duct tape
6. White streamers or toilet paper
7. Black Sharpie Marker
8. Baking soda
10. Plastic Wrap
11. Cork that will fit tightly in the opening of your water bottle.
|My son painted a headstone we made out of cardboard.|
|We added R.I.P.|
|Next, we taped a cardboard box to the back of the headstone with a hole cut in the top of the box. This hole was big enough to stand up the drinking end of a water bottle, but not too big that the bottle would fall through the hole.|
|It was time to design our ghost. We wrapped a plastic water bottle with white duct tape. Then, we taped on some white streamers and added a ghost face with a black Sharpie marker.|
|I poured vinegar into the bottle. I never measured, but it was probably about a 1/4 cup.|
|I tore a piece of plastic wrap and laid it flat on the ground. Then, I poured a pile of baking soda on it. Once again, I didn't measure. It was probably 2-3 Tbsps.|
