Ghost Bubbles! If you want to make any day better, perhaps the easiest way is to add bubbles to it. My personal favorite is Ghost Bubbles. They’re not that hard to make and they are great fun to explore!

Soap Powered Boat!How does it work?Water molecules are strongly attracted to each other and stick close together. This creates a strong but flexible "skin" on the water's surface called surface tension. Surface tension allows the cardboard boat to float on top of the water.Adding soap disrupts the arrangement of the water molecules. The water molecules near the detergent are attracted to the detergent as well as to other water molecules, so the surface tension of the water behind the boat decreases. Water molecules move from areas of low surface tension to areas of high surface tension. The boat is pulled towards areas of high surface tension by the water in front of the boat.

Discover the real taste of candy.Think of some of your favorite tastes: savory Thanksgiving turkey, buttery mashed potatoes, tangy cranberry sauce, and warmly spiced pumpkin pie. We perceive food's complex, layered flavors through the work of five* types of receptors on our tongues—those that detect either sweet, sour, salty, bitter, and umami (savory). These receptors bind to chemicals in our food and transmit the information about the chemicals to our brains, resulting in a healthy appreciation for the nuances of chocolate, coffee, strawberries, and more.

Backyard Bug BonanzaStep outside and discover the diversity of insect life in your neighborhood.Insects are the world’s most diverse group of living things, with over 950,000 identified species and counting. You might think that you’d need to travel to the Amazon to study insects, but they can be found practically everywhere—including right where you happen to be.

Make Your Own RainstickListen to the sound of rain falling—anytime, anywhere.The rainstick is a traditional instrument thought to have originated in Chile, where cactus spines are inserted into dried, hollowed-out cactus branches that are then filled with pebbles, raw rice, or dried beans.

Fog ChamberMake a portable cloud in a bottle: Now you see it, now you don’t!Clouds form when invisible water vapor in the air cools enough to form tiny droplets of liquid water. In the atmosphere, this usually happens when moist air rises to higher altitudes. At higher altitudes, the pressure is lower, so the gas expands, loses internal energy, and cools. You can create the same effect by rapidly expanding the air in a jar.

Make Your Own SeismographScientists study earthquakes so we can understand them better and hopefully one day predict them so we can save thousands of lives. A seismograph is a tool scientists use to record earthquakes and measure their strength. In this activity you will build your own seismograph using simple materials.

Make Tie-Dye T-shirts with Permanent MarkersHave you ever made a tie-dyed t-shirt? It can be a lot of fun to dye a shirt in bright colors with spiraling designs (especially when it is done on a warm day outside to prevent indoor messes)! In this science activity, you will get to dye a t-shirt with your own colorful artwork using permanent markers. Along the way, you will find out how solubility helps your drawings leave beautiful designs on the fabric.

Do you know anyone who has had a hand or an arm injured in an accident? What if you could build them a robotic hand to help them accomplish everyday tasks like writing, picking up a glass, or opening a door? This activity will show you how to build a simple robotic hand using common household materials.

Make a Paper CircuitDo you like arts and crafts projects like drawing, painting, cutting shapes out of construction paper, or origami? Instead of drawing that bright sun or lights in a house, imagine adding real lights to your artwork! This project will show you how, by introducing you to the world of electronics with "paper circuits." Paper circuits are made with just a few simple items; you can use a battery and some copper tape to add tiny lights to your project. The best part is that it is easy to do, and you do not need to know anything about electronics to get started!

Make Marbled Cards Using Science!Do you like both, arts and science? Then this is the perfect activity for you! You will create beautiful marbled paper cards and practice science at the same time! The only materials you need are shaving cream, food coloring, and sheets of paper. It might get a bit messy, but that is part of the fun!

Build a Bird Feeder to Study BirdsDid you know that there are about 10,000 different types of birds in the world? You don't have to go far to see some of them. Birds live outside in backyards and parks and can even be found in a busy city! Do you know what kinds of birds live in your neighborhood? Have you ever taken a close look at the birds you see in your backyard to identify them and observe their behavior? In this activity, you will build a bird feeder to attract birds, so you can study them.

Build a Paper Roller CoasterHave you ever ridden a roller coaster? Have you ever wanted to design your own? There are plenty of expensive toys and even video games that will let you build your own coasters—but in this project you'll make one out of paper and tape, and learn about roller coaster physics along the way!

Turn Milk into Plastic!Have you ever heard that plastic can be made out of milk? If this sounds like something made-up to you, you may be surprised to learn that from the early 1900s until about 1945, milk was commonly used to make many different plastic ornaments, including buttons, decorative buckles, beads and other jewelry, fountain pens, the backings for hand-held mirrors, and fancy comb and brush sets. Milk plastic (usually called casein plastic) was even used to make jewelry for Queen Mary of England! In this activity you will make your own casein plastic out of hot milk and vinegar.

Balance the Forces Within a MobileHave you ever seen a mobile? Not a mobile phone, but a hanging art sculpture. You might have had such a mobile in your room when you were little. These mobiles hang from the ceiling and are usually made up of many layers of rods to which lots of differently shaped objects are attached with strings. When you look at the mobile sculpture, you might wonder how it can stay balanced all the time even when it is moving in the air. In this activity, you will make your own mobile sculpture and find out how it stays balanced.

Junkbots: Robots from Recycled MaterialsBuilding "junkbots" is a fun activity where you can turn recycled materials—like plastic bottles and cardboard tubes—into robots! This is a great activity for a classroom or a group of friends, because you can race your robots against each other and even make them sumo wrestle. You do not need any previous experience with robotics to build junkbots. A Science Buddies kit is available with all the electronic parts you need, including motors, batteries, and clear instructions for how to connect them. Gather up some recycled materials and get started!

Did you know that gears are all around you? You can find them in wind-up toys, bicycles, carousels, cars and trucks, cranes, drills, wind turbines, analog watches, and so forth! If you've looked closely at a moving bicycle, you have seen gears at work. Are you curious about their purpose? In this activity you will use candy to make gears and explore why they are so versatile.

Have you ever wondered what a parachute and an open rain jacket have in common? They both trap air and slow you down when you move fast! In this activity, you design a parachute for a miniature action figure. Tissue paper or a plastic bag and a few strings is all it takes to make your figure into an expert skydiver.

Do you love playing on a seesaw? Why is it that depending on where you sit on the beam, and the weight of the person on the other side, you either fly up into the air or fall down to the ground? And why is it so difficult to perfectly balance the seesaw? It can all be explained with physics! In this activity, you will investigate the balancing forces of a seesaw—with a seesaw made of candles!
