Welcome to Camp Grandma’s Gassy Balloon Show, brought to you by my Science Guy Grandsons.  Nearby is Copper, our sulking grand-dog, since this project didn’t include snacks.

Camp Grandma Science Project 2 Supplies needed:
Plastic Water Bottle
Vinegar
Baking Soda
Balloon
Funnel
Food Coloring (optional)

1). Pour 1/4 cup of Vinegar into an empty plastic Water Bottle.

2). Insert a Funnel into the Balloon.

3). Pour 1 Tablespoon of Baking Soda into the Balloon through the Funnel.

4). Remove the Funnel and carefully attach Balloon to the Water Bottle without letting any Baking Soda spill into the bottle.

5). Lift the Balloon up so the Baking Soda falls into the Bottle.

Now the fun begins!  Watch the balloon inflate.

My Science Guy’s project is a success.  The Vinegar and Baking Soda react when mixed and produce Carbon Dioxide gas.

This bubbling gas causes the balloon to inflate.

After the bubbling action stopped and the balloon deflated, the Science Guy’s were ready to add a few drops of food coloring to a fresh mixture.

This made for some interesting green bubbles that re-inflated the balloon.

How many times did my Science Guys try this project?

Hint: A quart of vinegar makes for a fun afternoon.

Isn’t science a gas?

My thanks to Life Is Peachy for this great science project idea.

When the grandkids come over, my kitchen becomes “Camp Grandma” and today we created homemade erupting volcanos.volcano with sand decoration

 

 

 

 

 

 

 

 

 

Items needed:  a round pie plate with heavy duty tin foil, a small glass bottle, lots of newspaper and paper toweling, and coarse sand for that earthy look.  This play dough recipe worked great when shaped around a glass bottle to look like a volcano.volcano tutorial

Homemade Play Dough Recipe
2 cups  Flour                 1 cup Salt
2 tbl. Vegetable Oil        2 cups water
4 tsp. cream of tartar
Pour all ingredients into a large pot.  Stir constantly over medium heat until a dough ball forms.  Knead dough until the texture matches play dough (1-2 minutes).  Store in a zip lock bag or plastic container.

shaped volcano with lintThe play dough packed glass bottles are then placed in the tin foil covered pie pans for mess control.  Some dryer lint soaked in white glue was packed on the volcano for decoration.

Insert a funnel into the glass bottle and pour in 3 tablespoons of Baking Soda.  Mix 6 drops of dish soap and 4 drops of red and yellow food coloring to 2 cups of vinegar.

The grandkids played for hours with their volcanos and eventually used an entire gallon of vinegar.  Total cost for this project was less than a few dollars, but time spent was priceless.
