Problem: Article: Put up a sign at each corner, numbered 1, 2, 3, and 4. You can label the corners with colors or words instead. If you're a teacher, try using something related to today's lesson. Clear the area near all four walls, so children can easily move between corners. The volunteer gets to stand in the middle and count down. Tell the players the rules of the game:  The person in the middle will cover her eyes and count down from 10 to 0, loudly and slowly. Everyone else moves to one of the four corners, very quietly. When the person in the middle finishes counting, she chooses a number from 1 to 4 (with her eyes still closed). Anyone standing in the corner she chose has to sit down. Anyone who isn't in a corner when the counting is done has to sit down. After each round, the person in the middle can open her eyes and see who she knocked out. Then she closes her eyes again and counts from 10 to 0. Each round works the same way. Whoever is in the corner she chooses each round has to sit out for the rest of the game. Once there are only a few people left, the game can take a long time to finish. Add extra rules to speed it up:  Once there are eight people or fewer, each corner can only hold 2 people maximum. Once there are four people or fewer, each corner can only hold 1 person maximum. Once one person is left, that person gets to move to the center and count. Everyone else can stand up again and play for another round.
Summary: Number the four corners of the room. Make space at the sides of the room. Ask for a volunteer to be "It". Explain the rules. Keep playing with the remaining students. Adjust the rules once most people are out. Play until there's one winner.

Problem: Article: Many cities will require building permits for installing hot tubs outdoors. Check with yours to see if you need to as well. Make sure the spot you choose is large enough for the hot tub as well as some extra leeway for getting in and out and performing maintenance. A safe amount to allot is approximately 10 feet (3.0 m) by 10 feet (3 m by 3 m), but it depends on the size of your hot tub.  Examine your city's building code to ascertain how far away from your home you must place your hot tub. Many codes require at least 5 feet (1.5 m) of clearance between your home and your property line. Two other regulations you need to consider when finding a place for the hot tub. The hot tub should be at least 10 feet (3 m) away from any overhead power lines, as well as 5 feet (1.5 m) removed from the spa panel. Water and electricity do not mix. Hot tubs, when full, can weigh as much as 3,000 pounds (1,361 kg). For this reason, you will need a firm foundation on which the hot tub can rest. If you don't have a firm foundation, you risk damaging the tub voiding any warranty it comes with.  Pouring concrete into a 3 to 4 inch thick (7.62 to 10.16 cm) pad is a common method of creating a solid foundation. Concrete provides a very strong foundation. At the same time, it may not be aesthetically pleasing and will be permanently anchored into place if you ever choose to move the hot tub. Another option is prefabricated spa pads. These pads have interlocking grids that make installation easy, and they can be removed if you ever decide to relocate your tub. At the same time, spa pads may be less supportive than concrete. Make sure you have a solid base to work with, and you choose the strongest pads if you use this option. If you want to place your tub onto a deck, check first with a contractor. They should be uniquely suited to tell you whether the deck will be able to withstand a ton or more of weight bearing down on it like a continuous hammer. The last thing you want to have happen is to break your deck, and then your tub, upon installation. Most modern tubs are self-contained, meaning you won't have to run any plumbing in order to get the tub up and running. But electrical wiring is another matter. Cities usually have codes for using certain types of conduits, so make sure you talk with your local building department. When you have, decide if you'd like the conduit to run under or above ground. Most pumps will require an extra hard-wired circuit, one that's entirely dedicated to the electrical on the tub. A 240V, 50-amp GFCI (Ground Fault Circuit Interrupter) should be sufficient on many tubs. Multiple-pump tubs may require a 60-amp circuit. If you don't have familiarity wiring this kind of circuit, it's best to call an electrician to do it for you.
Summary:
Check to see if you need a building permit. Choose a location for your hot tub. Prep the site, if necessary. Call a general contractor if you decide to place your tub on a deck or build a deck to accommodate the tub. Create a route for the power to reach the hot tub.
