We spent about 2 hours at the beach but later than normal grabbed a pizza for lunch and then some chill time. The boys played in the pool while I cooked dinner (We got one at Toys R Us on sale). Then it was time for bath and then we made lava lamps at the end of the day.
Materials:
Water Bottles (We already had some)
Cooking Oil ($1.50)
Food Coloring (Left over from bouncy balls)
Water (free)
Alka Seltzer Tabs (I got generic ones from Walmart for ($2.57)
Step 1: Fill the water bottle 2/3 full with cooking oil
Step 2: Fill it up the rest of the way with water
Step 3: Add desired food coloring
Step 4: Add Alka Seltzer
Make sure that you do not put the lid back on the water bottle the pressure needs to escape. Putting the lid on will cause the pressure to be too much.
The best part about this is that you can always just add the tabs again as you want to add it to your daily craft schedule but might not have the time to do a full craft.
Here are the results of our lava lamps.
This is right before we added another tab. Aiyden is giving a thumbs up! |

Watch them bubble up |
Bubbling with the Alka Seltzer Tabs |
We started asking them questions about oil and water and making this a real experiment and learning opportunity. Some of these are questions you ask during the experiment and others you can ask during or after. Make it a real lesson but fun....or just make it because it's cool
- Why don't oil and water mix?
- Let's talk about density.
- What happens when you add water to the plastic bottle? Why do you think this occurs?
- What happens when you add the food coloring to the bottle? Why do you think this occurs?
- What happens when you add the Alka-Seltzer to the bottle? Why do you think this occurs?
- What experiments did you perform on the closed soda bottle (twisting, shaking, etc.)? What did you notice during each trial?
- Does the temperature of the water affect the reaction?
- Does the size of the bottle affect how many blobs are produced?
- Does the effect still work if the cap is put on the bottle?
Does the size of the tablet pieces affect the number of blobs created?

We had a really good day. A great way to start the week. Tomorrow is full of more fun including $1 movies, free bowling, moon sand and night bowling. Until Next Time!!!
