Before you begin working with acids, it’s important to wear the proper protective gear. Wear long sleeves that cover your arms as well as chemical resistant goggles, gloves, and apron. You also should have access to a fume hood that you can work under. Bring all your supplies into a well-ventilated laboratory and place them next to the fume hood. Set up a bowl of baking soda in the case of an acid spill. Sodium bicarbonate neutralizes acids and makes spills less harmful and dangerous.  Make sure that the fume hood works before you begin working. In case of an acid spill, pour the baking soda over the spill. You will see bubbling, which means that the neutralization is taking place as gaseous C02 is released. Test the pH of the spill with pH paper. Once it’s between 6 and 9, it’s safe to wipe the spill with a sponge and wash the material down the sink. You can create flash paper out of tissue paper, toilet paper, or even a cotton T-shirt. Just make sure that whatever paper you use is 100% cotton. Cut out however many sheets as you want into roughly the same size as a business card. Under the fume hood, pour concentrated nitric acid and concentrated sulfuric acid into a 1 liter (0.26 US gal) (4.2 cup) pitcher in a 5:4 ratio (5 parts concentrated nitric acid to 4 parts concentrated sulfuric acid). Make sure that you have enough liquid to eventually submerge the paper. Stand outside the fume hood, with the beakers and acid inside the hood. Place your gloved hands inside the fume hood and do all your work at least 6 inches (15.2 cm) in from the hood opening. To mix the two acids together, hold the pitcher and lightly swirl it with a slight motion of your hand. Do not shake the acid or swirl it vigorously, as this can cause the acid to splash.

Q: Cavaliers are gentle good-natured dogs, but, as with all canines, they enjoy the sense of security associated a capable owner who demonstrates they are in charge. Training sessions should be reward-based and clicker training lends itself ideally to this.  The principle behind clicker training is that the dog associates the click-clack of the clicker with a reward. When the dog shows a desired behavior (such as "sit") the click-clack marks the exact moment being rewarded, which helps the dog understand what behavior earns a reward. Then a cue word "Sit" is added to the click-clack, and eventually the clicker noise dropped in favor of the command. Good basic commands to teach are Sit, Stay, and Come. This equips you with good control of the dog because you can stop them and recall them to you, whatever the circumstances, hence keeping the dog safe. Your Cavalier will love the one-to-one time with you, so training generally strengthens the bond between you. Try to schedule two, 10 - 15 minutes sessions a day. Cuddle it, snuggle it, and pet it every day. What a Cavalier wants most from life is to be loved and adored. Make sure you don't disappoint your dog by ignoring it. The love you give you will get back ten fold from your Cavalier.
A: Train your Cavalier. Spend time training your dog every day. Lavish your Cavalier with love.

You want the kind that sprays with a foam and hardens. You may want to try Great Stuff Insulating Foam Sealant. Once your basic shape is formed, allow it to dry.  Place a small piece of paper atop it. Drop 4 Mentos into the cylinder. Quickly remove the paper that is lying flat over the top of the soda bottle. The 4 Mentos should pour into the bottle starting the explosion.   The porous surface of the Mentos causes the rapid formation of carbon dioxide. This chemical reaction produces foam.   Remove your 2 l bottle of soda from the bottom of the cardboard. Insert another bottle and do it again.
