Problem: Article: If you're only running cold water to your shower, chances are good you won't be spending hours getting wet. As such, drainage should not be a major concern. Still, you need some layer between your feet and the ground, otherwise you'll end up with dirty, muddy feet after every shower. Gravel is by far the most common bottom for outdoor showers. It is easy to install, looks good, and naturally drains away water if you take shorter showers. You can buy gravel, river pebbles, or small stone mixes depending on your aesthetic desires. To effectively install a gravel floor:  Smooth out the flooring the best you can. Lay down your stones around the shower. For a more professional look, use half-buried 2x4s to create a simple enclosure around your shower that will hold the gravel in. Use a tamper to press the gravel tightly together, leaving you with a smooth, regular floor. You'll need one 8-foot 4x4" piece of wood and one 8-foot 1x4" piece, both pressure treated. You'll use the first piece to build a square base for your floor, and the second piece to put together the drainable flooring. For a cheap, pre-made alternative, consider using a wooden pallet.  Cut one of the 4x4's into 4 even pieces, then screw them together into a simple square frame. Cut a 1x4" into 7 individual pieces, each 26-1/2" long. Place your 7 pieces onto your board starting on the edge, each piece parallel to the next. Leave a 1/4" space between each board for water to drain through. Screw the floorboards into the wooden frame. The easiest way to make a shower wall is to set up four more posts (identical to the one holding up your piping) in the ground, then nail plywood sheets to the posts as walls. You can then attach decorative shingles, paint or stain the plywood, or add a door/curtain instead of wood for one of the sides. You can get a set of outdoor shower walls from a variety of places, and there are a lot of different sets out there that can make your life much easier. However, these sets can run up to $1,000, so it may be more cost-effective to build your own walls instead. This strategy, of course, only works if your shower is attached to a wall or fence. That said, a simple curved shower rod can cover up the other 3 sides and leave you an easy, breezy outdoor shower experience. An outdoor shower will be up against the elements, and regular water will warp and ruin wood if you don't take precautions. Use an outdoor sealant and finisher to protect your shower for years to come.
Summary: Consider how much drainage you'll need when constructing the floor and walls. Tramp down a thick layer of gravel for easy, cost-effective flooring. Build a simple wood floor for a professional looking shower. Use plywood or corrugated metal sheets with wooden posts for a simple, customizable wall. Purchase pre-built outdoor shower walls for a professional, easy finish. Use a curved shower curtain to build an easy wall around your shower. Stain and finish any wood so that it is waterproof.

Problem: Article: To get the pieces of egg back out of the bottle you will need baking soda, vinegar, and a plate. This experiment is essentially the reverse of what you did to get the egg into the bottle. You will increase the air pressure inside the bottle so the egg will get pushed back out. You need about 2 tablespoons (30 ml) of baking soda and 3 tablespoons of vinegar.
Summary: Gather the necessary materials.

Problem: Article: Put the berries in a strainer and hold it over the sink under the faucet. Turn on the cold water and rinse the strawberries off thoroughly to remove any dirt or grime. If your faucet has a spray nozzle, use this to give the berries a shower and cover more surface area at once. Hold a strawberry in 1 hand and pinch the green top leaves firmly between 2 fingers on your other hand. Gently twist and pull to remove the stem. The stems are edible, but they don't have a nice taste or texture, so removing them leaves you with just the tasty berry.  Don’t slice off the tops because it just wastes some of the tasty red fruit near the top. Make sure to wait until after you wash the strawberries and are ready to slice them to remove the tops.
Summary:
Rinse the strawberries under cool water. Pick the green top stems off every strawberry.
