Article: If you plan to take your rabbit outside of your home, you’ll need a leash so that it doesn’t get away. Harness-style leashes are the best option for your bunny because they minimize the risk of discomfort or injury.  Look for harnesses, which go around your rabbit’s chest and torso, in the rabbit or cat aisles of your local pet store. You want something that is lightweight and no more than 6 feet. Remember that your rabbit will technically be walking you. The harness and lead is simply to give your rabbit a gentle tug if he is going into danger, and to give you a feeling of being in control. Try and find an H-style harness, which looks like an H when laid out flat. You can also get a figure-eight style harness, but be aware that there isn’t a consensus on whether they’re safe. These style harnesses can cinch your rabbit’s neck and cause injury. Avoid collar leashes because your rabbit can easily slip out of them or get injured. Once you’ve purchased the harness, you’re ready to put it on your rabbit. Making sure it fits properly can keep your bunny from escaping as well as prevent discomfort and injury.  Kneel on the floor beside your rabbit and hold it gently, but firmly. Make sure to pet your rabbit and speak to it soothingly while you easy the harness on to it. Consider giving your bunny treats while you’re putting on the harness. This can help your rabbit associate the harness with a positive experience. Make sure the harness is snug, but not too tight on your rabbit. A harness that is too loose can result in your rabbit escaping and one that is too tight can cause discomfort or injury or may keep your bunny from moving. Your rabbit might be a bit resistant to its harness at first. Your rabbit may even demonstrate antics, which shouldn’t alarm you—you’re not hurting it. Giving your rabbit a few days to get used to the feel of the harness and associate it with something fun can make your walks enjoyable.  Take the harness off if your rabbit is reluctant to wear it. Try again slowly later the same day or even the next. Keep doing this until your rabbit feels comfortable with the harness. Attach the leash to the harness once your rabbit is used to wearing the harness indoors. Then let your rabbit drag the harness and leash behind him or her until he or she is used to the feel of a pull on it. You can do this by putting on the harness twice a day for 5-10 minutes for a week. Offer treats so that your rabbit moves and associates the harness with fun. Some local humane societies or even rabbit clubs may offer leash-training classes for your rabbit. If you are having trouble getting your rabbit used to the leash or just want some more information, consider enrolling in a leash training class. Call your vet, local humane society, or local rabbit clubs to inquire about upcoming classes.

Problem: Article: You can pretty much eyeball this one -- if it looks like it's in okay condition, it's probably safe to use.  Be sure to have dry hands, wet hands is a safety hazard with and electric appliance. Remove the blender from the base and wash the two parts separately. Just run the top under warm water with a little soap; the blades are sharp so be careful not to cut yourself.  Never, ever, ever put the base in water! If you get it gunky, take a wet cloth or sponge to it. It's hard to hurt it -- and water (or any other liquid) is really the only way. Be sure to dry the blender completely, you don't want to leave liquid in the blender, its best to air dry upside down.
Summary: Make sure the blender is plugged in, clean, and in working condition. Clean the blender.

The battery is needed only to send an initial current through the wire to cause the hydrogen in the water molecules touching the electrodes to separate from the oxygen, forming bubbles around the electrodes. This process is called electrolysis.  Notice the bubbles forming around each electrode. One electrode has bubbles of hydrogen, while the other electrode has oxygen bubbles. The battery source does not need to be completely attached the clip, just touched to the battery terminals to begin the reaction. The battery is only needed to initiate the reaction. The separated hydrogen and oxygen will recombine into water, releasing the energy originally used to split them as electricity. The platinum in the electrode coils serves as a catalyst to speed the recombination of the hydrogen and oxygen into water molecules. Initially, the output may be as great as two volts, but will decline as the hydrogen bubbles dissipate, quickly at first and then gradually as the last of the bubbles pop.  A light bulb or LED may appear bright initially, but will quickly dim and then gradually fade away.
