When I saw the little bee checking out me and my camera, I wondered what he saw. I did a little looking around the Internet and found a cool website by Andy Giger that gives our best guess for what a bee sees when it looks at an object. Since he says the images are available for downloading, here is what the bee might see when it looks at my face.

The images are black and white because bees see color differently than we do. They do not see red (one reason so many bird flowers are red) and they see colors in the ultraviolet range which we can't see. If I was wearing red lipstick, the bee would have probably seen something closer to black or dark gray.bee eye view

This tiny bee is known as a digger bee. The flower it is visiting is a penstemon. Digger bees are fun to watch because they are cute and furry. This one was definitely aware of me. It came over and checked me out a couple of times. I wonder what I looked like to it?

If you are interested in bees, you should check out my lesson plans titled "Africanized Honey Bees on the Move." Some of the lessons have information about solitary bees such as this one.

Today let's do some bubble science. Most of us have used bubble formulas or solutions sold in stores, and they make great bubbles. But what if you are out of bubble formula and can't get to the store to buy any? Are there any other products you already have around the house that will make bubbles? You probably can think of a couple of things right off hand. Now let's give them a try.

Part 1. Testing the products
You will need:

-A bubble wand or similar tool for blowing bubbles, such as a spool
-A few small containers, such a small paper cups, big enough for the wand to easily fit inside
-Household products to test, such as dish detergent, shampoos, hair conditioners, toothpaste, laundry soap, hand soap, hand sanitizer, sunscreen and hand cream. You might also want to try blowing bubbles in milk and cream, without adding water. Use your imagination to come up with things to test. Note: Stay away from potentially dangerous products such as toilet bowl cleaners.

First, try to blow a bubble with just water. Can you do it? Put some water into a container, and then swish it with the bubble wand and blow. What happens?

Dump out your test compound after each test into a sink and rinse the container completely, or use a fresh container for each test so the products don't interfere with each other.

Squeeze a nickel-sized blob of household product in a container and add about the same amount of water. Stir the mixture with the bubble wand. What happens? Do any bubbles form? Now, load the wand and try to blow a bubble. Does it work? If not, try to add a bit more water and try again.

What about toothpaste? Doesn't it make small bubbles when you brush your teeth? Could you blow a bubble with your toothpaste?

After you have tested all the different products, which gave the best bubbles? Typically dish detergents and shampoos should work well, but some brands are better than others. If none of the products made good bubbles, then you might want to try again using bottled water with your products. Tap water can have minerals or other chemicals in it that make it difficult for bubbles to form.

Part 2. Improving the formula

You will need:
-Equipment from Part 1
-Household products that worked best for producing bubbles, from Part 1
-Corn syrup

Commercial bubble formulas often contain glycerin to help the bubbles last longer. But glycerin is expensive and may be an allergen. Will adding sugar or corn syrup make bubbles last longer?

Try this recipe. Mix 1/2 cup of your best product with 1/2 cup water in a container. Try a few bubbles. Then add 1/4 cup of granulated sugar and stir well. Try blowing a bubble. Do the bubbles seem any different after the sugar was added? What about the marks the bubbles leave after they pop? Do the marks seem different?

Now mix 1/2 cup of your best product with 1/2 cup water again. This time add 1/8 cup of corn syrup and mix well. What happens to the bubbles this time? Which mixture do you prefer?
