Warning.
Some combinations will produce gas that should not be inhaled, and others could be explosive.
Which two fluids do you want to mix in your bottle?
Vinegar and hydrogen peroxide are acids.Acidsare chemicals which easily give away electrons when in contact with bases.
Bases are chemicals which easily accept electrons.
Rubbing alcohol is a base.Basestend to take electrons.
Water is also apolarmolecule.
It will tend to pull apart other chemicals causing the to mix with the water.
This is why water is called the universal solvent, and is the best way to clean almost anything.
Some chemicals are more soluble, than others.Solublemeans they pull apart easily.
Finally, Each chemical has its own density.
Some are moredense, or heavier.
Some some are less dense or lighter.
Play around to find two fluids that behave in a way that will make your sensory bottle interesting.
Once youve chosen your two fluids, venture to add color.
Did your fluids easily accept the color?
You may want to change your choice of fluids.
Finally, fill your bottle using your choices of colored fluids.
Fasten the lid securely.
you’ve got the option to use hot glue to help prevent leaks.
Turn your bottle upside down and watch what happens.
What other combinations would you like to try?
Some other chemistry experiments you might want to try arePumpkin chemistryandValentines day experiment.
