What you will need to make your lava lamp science experiment is in this picture.
Build your own lava lamps.
Make your own lava lamp instructions.
Notice that the water sinks below the vegetable oil.
A lava lamp works because of two different scientific principles density and polarity.
Children should show an adult these instructions and ask for help and not attempt this on their own.
It will sink slowly beneath the oil layer creating lots of bubbles.
Break open an oil soluble marker or pen and place the inked felt into a container of benzyl alcohol.
Make this lamp only with adult supervision.
Remember that the colors will blend together so be careful of your mix.
Oil and water just do not mix.
The alcohol and oil used in this lamp are flammable and must be treated with care when heating them to get the lava moving.
I just made two different lava lamps using one color for each bottle.
It s a lot of fun if you have a group of children and each child can have their own supplies.
Watch your lava lamp erupt into activity.
Density is the measurement of how compact a substance is how much of it fits in a certain amount of space.
Then add water until there s around an inch remaining at the top.
When the bubbles have stopped dribble a couple drops of food coloring into the bottle.
Lava lamp science project.
Add about 8 to 10 drops of food coloring.
Lava lamps are both mesmerising and beautiful to look at and in this daily dose we re going to make our own.
You can also add some glitter for some extra bling.
As the reaction slows down simply add more alka seltzer.
First fill the empty water bottle about 2 3 full with vegetable oil.
Leaving it in longer will give a darker color but will also increase the tendency to bleed into the brine.
A few minutes is usually a good time to leave the inked felt in the alcohol.
Fill the rest with water leaving a little of space at the top.
Fill the bottle two thirds full of oil.
Make your own lava lamp.
This is a safe and fun science experiment you can do at home or in a classroom.
Watch what happens to the water with your kids.
I ll show you two different ways to make your la.
The food coloring droplets will fall through the oil and rest on top of the water.
Easy to make lava lamp science experiment.
The oil floats on the surface because the water is heavier has a higher density than oil.
