SHELDON: YOU MIGHT’VE HAD A LAVA LAMP AS A KID.
NOW, YOUR CHILD CAN MAKE ONE RIGHT AT HOME.
LAVA LAMPS ARE ALWAYS FUN AND COOL TO LOOK AT.
TODAY WE WILL LEARN HOW WE CAN MAKE ONE.
IT US ABOUT THE SCIENCE.
>> IT’S CALLED DENSITY.
DENSITY IS HOW MUCH SPACE SOMETHING TAKES UP, WHICH CAN
SEEM LIKE A TRICKY CONCEPT TO EXPLAIN, ESPECIALLY FOR KIDS.
THIS EXPERIMENT IS PERFECT FOR THAT.
WE WILL START BY MAKING OUR LAVA.
IT IS GOING TO BE THIS WATER WE WANT THE LAVA TO BE COLORFUL.
WE ARE GOING TO ADD FOOD COLORING.
WE ARE GOING TO GIVE IT A STERN WITH OUR SPOON.
AND THE WATER IS GOING TO BE OUR LAVA EFFECT.
NEXT WE ARE JU GOING TO USE SOME CANOLA OIL.
SHELDON: CAN I USE ANY OIL?
>> YOU CAN USE ANY OIL.
THAT IS THE COOL THING ABOUT THIS PROJECT LEARNING ABOUT
DENSITY, YOU WILL SEAT WHICH IS MORE DENSE OR LESS DENSE USING
DIFFERENT OILS.
WE HAVE BEAKERS HERE, BUT YOU CAN USE ANY CLEAR KIND OF
CONTAINER.
YOU CAN FILL IT THREE FOURTHS OF THE W WITH THE OIL.
PERFECT.
YOU CAN ADD MORE IN THEIR.
-- IN THERE.
WE WILL AD LAVA AND WE WANT TO PAY ATTENTION TO HOW THE WATER
REACTS AND OIL.
LET’S DO THAT.
SHELDON: IT SEPARATES.
>> IMMEDIATELY, RIGHT?
WE IMMEDIATELY NOTICED THE WATER SINKS TO THE BOTTOM.
THAT MEANS THE WATER IS MORE DENSE THAN OIL AND IT MEANS THE
OIL IS LESS DENSE ON TOP.
SO TO GET THE LAVA LAMP GOING THESE ARE ALKA-SELTZER TABLETS.
WE WILL BREAK THESE INTO PIECES AND DROP THEM IN AND SEE WHAT
HAPPENS TO OUR WATER AND OUR OIL JUST DROP THEM RIGHT IN.
WE DO SE THEY SINK DOWN AND WE START TO GET THAT REACTION.
WHAT I HAPPENING IS THAT THESE TABLETS ARE RELEASING GAS,
CARBON DIOXI AIR.
THAT IS MAKING THE WATE LIGHTER .
AS THE AIR IS RELEASING IT IS PULLING THE WATER AND EVENTUALLY
WE SEE WHEN THE AIR RUNS OUT THE WATER DROPLETS GET HEAVY AND
THEY SINK BACK DOWN TO THE BOTTOM.
YOU CAN AZURE OTHER TABLET IF YOU WANT.
-- YOU CAN ADD YOUR TABLET IF YOU WANT.
SHELDON: IT IS THERAPEUTIC JUST WATCHING THEM ALL.
SO IF YOU WERE TO USE ANY SPECIFIC TYPE OF WATER DOES IT
VE -- VARY?
IT CAN DEPEND WE WONDERED WHAT WOULD HAPPE IF YOU USED
SPARKLING WATER.
IF YOU WANT TO EXPAND, YOU CAN USE DIFFERENT TYPES OF WATER IN
DIFFERENT TYPES OF OIL THE OTHER THING YOU CAN DO IS
AFTER YOUR WATER SETTLES DOWN, ADD SOME SALT TO YOUR CONTAINER
AND SEE WHAT IT DOES TO THE WATER.
THERE ARE A LOT OF WAYS YOU CAN EXPAND YOUR KNOWLEDGE ON THIS.
THIS IS A VERY FUN AND EXCITING AND VISUAL WAY T EXPLORE
DENSITY.
SHELDON ANYTHING ELSE?
>> YOU CAN ALWAYS CHECK OUR WEBSITE FOR DIFFERENT PROGRAMS
WE ARE RUNNING AND COME IN AND IS SEE US AND DO SOME
EXPERIMENTS.
SHELDON: THANK YOU SO MUCH.
WE APPRECIATE IT.
SHELDON: THAT WAS SO FUN.
I CAN’T WAIT TO TRY THAT.
THE SCIENCE CENTER IS OPEN EVERY DAY FROM 10:00 UNTIL 5:00.
JACLYN: I HAVEN’T SEEN A LAVA LAMP SINCE I WAS IN FOURTH
GRADE.
SHELDON: I DIDN’T HAVE ONE, BUT OUR PRODUCER DID.
KELLIANN I DIDN’T HAVE ONE.
BUT I AM NOT GOING TO TALK ABOUT THAT.
SHELDON: WE ARE CURIOUS NOW.
KELLIANNE: YOU KNOW THE FISH TANKS BUT NOT THE REAL ONES, BUT
I HAD ONE OF THOSE.
YOU KNOW WHAT WE A
