The lava lamp was invented in 1960 by Edward Craven-Walker. The glass filled container with blobs of colored wax is fun to watch move around forming different shapes. Your family can make your own lava lamp with these easy instructions.

Making a Lava Lamp

What you need
plastic bottle
water
baby or vegetable oil
food coloring

Steps
1. Mix up water and food coloring.
2. Fill the plastic bottle ¾ of the way with oil.
3. Take your water mixture and pour in to fill the rest of the bottle.
4. Close the lid tightly.
5. Turn the bottle on its side and watch the colors move through the oil in funny shapes and blobs.

How does this happen?
The water and oil do not mix because the water has more density than the oil. So the oil moves around in the water.

Percy LeBaron Spencer, an American Engineer, invented the microwave in 1945. His inspiration came when he was standing in front of an operating magnetron (you can look up what that is), and his chocolate bar melted in his pocket. In honor of this invention look down for a microwavable S’Mores recipe.

Percy LeBaron Spencer changed the way we cook by accidentally standing in front of an operating magnetron. The first microwave named, the ‘Radarange’, was first sold in 1947. It was almost 5 ft 11 in tall, weighed 750 pounds and cost about $5000 each. That is like the size of a refrigerator. In 1967 the first popular home model, the countertop Radarange, was introduced at a price of $495.

“Do not be afraid” appears 365 times in the Bible. Hmm, same amount of days in a year.

The largest hamburger cooked in the world weighed in at 6,040 pounds.

About 6,000,000 pounds of space dust settle on earth every year.

“Lollipop” is the longest word that can be typed using only the right hand.

A chicken with red earlobes will produce brown eggs, and a chicken with white earlobes will produce white eggs. Look below to learn how to make a bouncy rubber egg.

Bouncy Rubber Egg

What you need
1 egg
1 jar
enough vinegar to fill your jar

Steps
1. Place a raw egg in a sauce pan and fill it with water.
2. With adult supervision bring the egg to a boil and cook for a further 10 minutes to make sure the egg has been cooked throughout.
3. Drain the boiled water from the pan and leave the egg to cool for a bit.
4. Gently place the hard-boiled egg in a glass jar.
5. Slowly pour in the vinegar until the egg is completely covered.
6. Screw the lid back on the jar tightly.
7. Keep checking your egg every day to see what changes are taking place.
8. Let the egg sit in the vinegar for at least one week.
9. After a week has passed; drain the vinegar from the jar. Rinse the egg under water and dry with a paper towel.

What happened to the eggshell?
The vinegar dissolves the eggshell and leaves you with a rubbery egg. Try bouncing the egg from a short distance; do not drop from a high height.

Fun fact: Vinegar has been around since ancient times.
