In one sentence, describe what the following article is about: Assemble all your supplies for this science experiment before you start. Have the following on hand:  1 US gal (3.8 L) glass jar with lid Aerosol (hairspray or air freshener) Flashlight or lamp Water Dark-colored paper and flashlight Put enough water in the jar to cover the bottom, or about 1 inch (2.5 cm). Swirl the water around so that the jar heats up. This will also prevent any condensation from forming in the jar. The jar will be very hot. Be sure to use oven mitts to hold the jar. Turn the jar lid upside down so that it’s a little bowl. Place two ice cubes in the lid. Lay the lid on top of the jar. You may now see some condensation in the jar. Use an aerosol product like hairspray or air freshener to spray into the jar. Lift the iced lid up and quickly spray a small amount into the jar. Replace the lid to trap the aerosol in the jar. Use a dark piece of paper to create contrast. This way, you will be able to see the cloud that has formed in the jar. You can also use a flashlight to shine into the jar. When you lift the lid off the jar, the cloud will float out. You can let it pass through your fingers. You created hot, moist air in the jar when you poured in the boiling water. The ice on the lid works to cool the air as it rises.  This water vapor will turn back into a liquid when it cools, but it needs a surface to condense on. When you spray the aerosol into the jar, you’ve given the water vapor a surface. The molecules stick to the aerosol and condense into cloud droplets. The clouds swirl around inside the jar because the air inside is swirling around. The warm air is rising while the cool air is sinking. You can see the movement of air as the clouds swirl.
Summary: Assemble your supplies. Pour boiling water into a glass jar. Place ice in the jar lid. Spray aerosol into the jar. Place a dark-colored piece of paper behind the jar. Open the lid and touch the cloud. Understand why this works.

With a little creative application, a single lemon can serve as both cleaning solution and sponge. Cut the lemon down the middle widthwise. You can now grip it by the peel-side and use it as a handheld scrubber to treat yucky shower stains.  Pick out the seeds before you start scrubbing so they don’t end up at the bottom of your shower. The natural acids in lemon juice are safe enough for you to use them to clean your shower as often as you’d like without having to worry about wearing down the acrylic finish. You may also have success using another type of citrus, such as grapefruit. Work the exposed fruit over the acrylic surface. As you press the lemon into the acrylic, the juice will gradually squeeze out, breaking up hard water stains, mold and mineral deposits.  After you’ve worn the lemon down, simply grab the other half or cut a new one and keep going over the area until it’s spotless. Just as a precaution, avoid using lemon in conjunction with other green cleaning ingredients like sea salt. Even water-soluble abrasives may be enough to scratch up acrylic. Once you’ve given the shower a thorough scrubbing, give the lemon juice a little time to work its magic. Though mild, the acids that the juice contains will usually be enough to deal with the majority of commonplace stains. The longer you let the juice soak, the better the end result will be.  Lemon juice is especially useful for dissolving stains that result from exposure to hard water or chemicals. Citric acid will not only clean and disinfect, it will also help brighten up the acrylic and restore it to its original luster. Flush every surface of the shower with warm water, taking care to get rid of any lingering juice or pulp from the lemon. If necessary, go back over the acrylic one more time with a soft towel or sponge. When you’re done, your shower should be pristine and have a fresh, clean scent!

One-sentence summary -- Slice a large lemon in half. Rub the lemon directly onto the surface of the shower. Allow the lemon juice to sit for 10-20 minutes. Rinse the shower clean.

Q: To find a vet that works with frogs, contact local veterinary schools or look online for lists of veterinarians that work with amphibians. For example, you can look at the website of the Association of Reptilian and Amphibian Veterinarians.  If there are several vets in your area who work with amphibians, make sure the vet you choose is the one that has the most experience with tree frogs. It's a good idea to find a vet before your frog is actually sick. Having an established relationship with a veterinarian that treats tree frogs will make it easier to get your pet quick care when it needs it. It is best to have your frog checked out by a veterinarian if you see a symptom of illness. While you may end up bringing your pet in for a problem that is non-existent, it is better to be safe than sorry. Some diseases require quick treatment in order to be eliminated. If you suspect that your tree frog is sick but you are unsure about bringing it in to be seen by a vet, at least call the veterinary office and talk to them. Tell them about your pet's symptoms and ask them if they think your frog needs treatment. If your tree frog is indeed ill, your veterinarian will begin its treatment and will give you instructions on how to continue treatment at home. Follow these directions and be sure to continue treatment for as long as your veterinarian suggests, even if your tree frog seems completely healed. If treatment is not minimizing your frog's symptoms or they are getting worse, contact your vet once again. It may be that your frog needs a different type or amount of treatment.
A: Find a vet that is experienced with treating tree frogs. Take your frog in for an examination. Follow your veterinarian's suggestions for treatment.
