 Hey again guys! In this post, I will show you how I made my Dense-O-Meter, and I'll also talk about emulsions.

MY DENSE-O-METER

~~~~~~~~~~~~~~~~~~~~

A Dense-O-Meter is a jar full of different types of liquid on top of each other. Whenever you drop a small item in it, it will either float on the top, or sink into a level of liquid. The level it sinks to is how dense the item is. (If you haven't seen the last post, density is the compactness of an item.) If you want to make a Dense-O-Meter, you'll need.....

- A Large Jar or Container

- Honey

-Light Corn Syrup

- Real Maple Syrup (I didn't have this)

- Milk

- Dish Soap

- Water

- Vegetable Oil

- Rubbing Alcohol

 (My Container was too full for the Alcohol)

- Food Coloring (Optional)

- Scotch Tape (Optional)
- Marker (Optional)
- Pipette

Once I got my jar set, I started adding the liquids one at a time. With the honey, corn syrup, and milk, I poured them down the center of the container so the liquids wouldn't mess up the other layers. The soap and water were a challenge. I had to squeeze the soap down the side of the container. The water was colored with food coloring to give some color to the Dense-O-Meter. I used the pipette to squeeze it down the sides so it wouldn't mix with the soap. With the oil, I just poured it down the sides, like the soap.

To test out the Dense-O-Meter, I got a washer, a carrot, and a plastic model of the Eiffel Tower. Here are the pictures of the Dense-O-Meter.

Density Levels

Density Level Labels

 In the pictures, you can see the washer in the honey, and the Eiffel Tower in the corn syrup and milk. Where's the carrot? If you check the dish soap level, you can see a bit of orange. The denser the item, the lower it sinks.

EMULSIONS
~~~~~~~~~~~~

We all know that oil and water don't mix, but how do we have so many things that have oil and water mixed in? The answer, is using an emulsifier. Emulsifiers are like magnets that attract both oil and water, that's how oil and water can mix. We can make certain foods called "Emulsions," like dressings, mayonnaise, and ice cream! They use emulsifiers to mix the oil and water  together. After a while, the oil and water might separate.There are many emulsifiers like egg yolk, tomato paste, Dijon mustard, etc.

Oil + Water = GROOVY! : Part 1

 Hey guys! In this post, I have a speed video for my lava lamp for my oil and water tinker crate. I will talk about haw a lava lamp is so groovy. (Yep, that's a question in the tinker-zine.)

WHY IS A LAVA LAMP GROOVY?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Have you wondered why a lava lamp was groovy? If you have, here's my answer. I think it's because oil and water just don't want to mix. If you look at a mixture of oil and water molecules, it looks like the oil molecules don't want to be around the water molecules. AKA, Hydrophobic. Just like the phrase says, "Oil and Water Don't Mix."

 You might be thinking, "How come the water is always on the bottom?" Good question! It's the density of the water. Density is how compact something is. Water is denser than oil. When you use the pump on the lava lamp, the air pushes up the water, meaning that having air mixed with the water gives it a lighter density! That's how my lava lamp works. Real lava lamps use heat instead of air to work. Instead of oil, there is a wax mixture that has a heavier density than water. It has a much lighter density once it heats up, which lowers the water. Once it cools off it lowers again, which switches the wax and water over and over again. The switching gives it a sort-of lava effect.

Magnetism Tinker Lab : Part 2

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
Hey again guys! Today I will be showing you my projects.

JUMPING TOY

~~~~~~~~~~~~~

This toy was pretty easy to make, I just needed....

- Tape
 - Small Toy
 - Bottle Cap
  - 2 Ring Magnets
 - Paper

First, I took the bottle cap, and taped a ring magnet on the inside of it. To make it bounce, I flipped the magnet to repel the magnet in the bottle cap, then I taped that magnet to the piece of paper. I completed the toy by taping the small toy to the bottle cap.

HOME-MADE COMPASS

~~~~~~~~~~~~~~~~~~~~~

This project was a bit challenging, but I was able to make it.

- Bowl of Water
- Cork
- Paper clip
- Ring Magnet

I took the paper clip and bent it straight. To make the paper clip work like a compass needle, I magnetized the paper clip with the ring magnet. Then I stuck it through the middle of the cork. It took a couple of tries, but I managed to get it through the cork. I gently put the cork in the bowl of water. When it stopped spinning in the bowl, it was pointing North/South. Then I used the magnet to see if the needle would follow the magnet.

WACKY PENDULUM

~~~~~~~~~~~~~~~~~~

This project is my favorite one. Here are the items I needed.....

- Pencil
- Tape
- String
- Straw
- Grey and Orange Foam (Small Hole)
- Ring Magnet
- Tinker Crate Box
- Scissors

To make the base, I flipped the tinker crate box to the side so the long sides are facing up. The pendulum needed a place to hang, so I taped the pencil on to the tinker crate box. The pendulum was pretty easy to make. I put the foam on the magnet, orange on the top and grey on the bottom. Then I cut the straw into a small piece, and slid it into the magnet. I hung it by slipping a piece of string into the straw, and tied it on by looping it around the string at the top. To finish the pendulum, I tied and taped it on the pencil. Another magnet that repelled the pendulum had to be on the surface so the pendulum would move in different directions. Here is the video of all of the magnet projects.

Do you know what a magnetic field looks like? If you were wondering what a ring magnets field was like, it would probably look like the picture below. When you feel the magnets attracting each other, that means they are within the magnetic field. The size may vary depending on the size and shape.

Hey guys. The camera broke and I have no un-boxing video. The items in the tinker crate were...

Ring Magnets X9

4 Piece Wood Frame Set

Notepad

Pencil

Pencil Sharpener

Acrylic Rods X2

Plastic Tube

Metal Cone

Magnet Guide

Mini Rubber bands X4

Sticky foam

Blueprints

Tinker-Zine

THE FIRST MAGNET, MAYBE?

~~~~~~~~~~~~~~~~~~~~~~~~~~~

Have you ever wondered where the first magnet came from? Once upon a time, there was a man named Magnus. One day, when he was keeping an eye on his sheep, his sandal stuck to a rock. Something was keeping the nails in his sandal attached to the rock. That something was magnetism. We don't know if it's true, but its a theory.

MAGNETS AND THEIR USES

~~~~~~~~~~~~~~~~~~~~~~~~~~

Magnet's have many uses. Magnets are used in refrigerators, DVD players, speakers, and more. Roller coasters use magnets too! That's right, roller coasters use magnetism to make the ride really fast. Older ones use gravity. There is a train that uses magnetic levitation (Maglev) to get around really fast. It's all the way in Shanghai. One is being built in Japan, but it won't be completed for another 11 years. NASA is making a rocket sled that goes into space. It has a track like a roller coaster, that uses maglev, and a sled with a shuttle attached to it! The track has to go up the side of a mountain to work. Small models are being tested today, but we don't know what the future has in store.

Maglev Train

Maglev Sled

 MAGLEV PENCIL HOLDER

~~~~~~~~~~~~~~~~~~~~~~~~

 Magnetic Levitation is important, but holding a pencil? It's possible with the items listed below.....

6 Ring Magnets

Wood Frame Pieces

Pencil

Pencil Sharpener

2 Acrylic Rods

Metal Cone

2 Mini Rubber Bands

Sticky Foam Rings and Pads(Grey and Orange)

 Before I could start on the main frame, I had to label the magnets first. When all of the magnets were stacked up, I put an orange foam ring with a large hole on top of the top magnet. Then I took a grey foam ring, took the top magnet off the stack, and put the ring on the bottom of that magnet. I repeated with the rest of the magnets, two of the magnets had foam rings with large holes, and the other ones had foam rings with small holes.

 When it was time to make the frame, I stuck the foam pads on to the large frame pieces. Then I completed my frame by attaching the large pieces to the long pieces that supported the frame. Taking the 4 magnets with small holes, I slid two magnets on each of the acrylic rods. I attached the rods to the large pieces and adjusted the rods evenly.

 The main part was done, but I needed the pencil tube done. I got the metal cone and slid the mini rubber bands on it so when the cone was slid into the end of the straw, it would be firm in place. To make the pencil tube float, I slid the magnets on the tube and positioned them with the magnet guide. All I needed to do was put the tube in between the rods and slide the pencil into the tube.
