Day 2 of the Bombing Boys Club.
On day 2 we learned how to clean pennies. We used salt and vinegar. After, the old pennies became very clean.
See the shiny pennies?
Next we made lava lamps. Mr.Timbit 's lava lamp was green and mine was blue. It was very fun. To make them we put food colouring in a water bottle. Then we added mineral oil and salt and bubbles came up.
Then we added some magic balls. They will grow bigger in a couple of days.
These are pictures of our lava lamps.
Next we made hand grenades. In a small ziplock bag, we put 3/4 cup vinegar. Then we wrapped up 3 tablespoons of baking soda in a small piece of paper towel. Carefully we put the baking soda packet in the bag, but not touching the vinegar, and zipped the bag close. When we were ready, we shook it and threw it. The first time, we were nervous. But the second time was exciting. POP! They blew up like that.
IT WAS FUN!
My first time - I was nervous.
This is what it looks like after it blew up.
baking soda + vinegar (in a zipped bag) = explosion
