Tape one end of the foil to the funnel model lightly. To make the foil funnel, wrap the foil around the model. To finish the funnel, tape the opposite end of the foil together. To ensure that the tape attaches completely, line the whole edge with it. Let the foil dry for several hours or overnight.
This is an easy way to create a disposable funnel for small batches of glue or paint. Just be sure to write the ingredients down on the back of the foil so you know what you're dealing with if someone gets burned by it!
Funnel making can also be done with plain paper bags. Just like with foil, start at one end and carefully roll up the bag until you get to the other end where you'll need to tape it shut.
This method is useful when you don't have any plastic containers available. You can use regular old coffee cans or juice boxes as long as they are all same size or similar shape.
Coffee filters work well too. They are usually available near the trash bins at grocery stores and come in different sizes. The most common sizes are 12-15 inches wide. You can use these by themselves or cut them into thirds lengthwise then fold each section in half widthwise.
The final type of funnel involves cutting holes in some kind of container.
How to Build a Funnel
Simply wrap some foil into a funnel shape and insert the little end into the neck of your preferred container. I'd recommend rolling it many layers thick to prevent it from being thrown out of position by a jet of liquid, but it should be alright if you pour carefully.
Funnels made from regular old-fashioned office supplies such as paper or plastic can also work well for pouring purposes, as long as they're not too thin or small. You want something that's big enough to allow most liquids to be poured in a controlled manner.
Foil funnels are useful for testing the depth of containers without filling them up all at once. They're also good for creating special effects during science demonstrations or when playing around with ingredients.
There are several different methods used for making foil funnels. Here are two easy options:
1 First, you'll need to create a template using cardboard or plastic sheeting. Use this template to cut several identical sections from aluminum foil.
2 Alternatively, you can use existing shapes as templates. For example, if you have a bowl or cup that isn't serving another purpose, you can use it as a mold for making funnels. Simply cut out several identical sections from aluminum foil and let them dry overnight before removing the template.
1. Fold the filter paper in half twice in a row, forming a 90-degree angle in the center. 2. Fold one side of the folded filter paper into three layers, then fold the other side into one layer to form a funnel. 3. Cut off the bottom of the funnel, if needed, so it is flat.
This is how you make a simple paper funnel:
1. Start with a piece of filter paper that is about 1/4 inch thick and 10 inches long.
2. Fold the filter paper in half lengthwise, making sure there are no wrinkles. Make another fold perpendicular to the first fold. This should create four layers of paper.
3. Next, fold the top quarter of the paper down toward the middle. Repeat this process on the other side. You should now have a funnel that stands up by itself.
Here's how to use the paper funnel: Pour the liquid into the center hole, and let it drain through the paper into the container below. As the liquid fills up the funnel, push the material towards the bottom of the funnel to start new layers forming on top of old ones until all the liquid has been drained.
The paper funnel is useful for draining small containers like jars or bottles.
Do you require a funnel? They're all around you.
Simple Paper Funnel
Cut the foil into little squares, roughly 1 inch by 1 inch, unless you're using a smaller ball, in which case your squares should be a sufficient size. Apply the square pieces of foil around the ball in precise lines using white craft or wood glue until the ball is completely coated. Let it dry completely before use.
Aluminum foil makes an excellent reflective surface for parties and other celebrations because it's easy to work with and very affordable. The only thing you need to remember when using it as a disco ball is to cover the entire surface in straight lines from corner to corner and from top to bottom. This will help the light reflect evenly all around the ball.
You can also buy pre-made disco balls that are covered in plastic or metal mesh. These look beautiful but are expensive.
Do not use regular glass or ceramic plates as mirror surfaces because they tend to break under the stress of dancing lights. Also, avoid using silver or gold foil because it will not reflect light well. It's better to go for black or white if you want your ball to shine brightly.
Foil can be cut easily with scissors or a knife and glued into place. Be careful not to damage the surface underneath when cutting shapes out of the foil. If you do get any scratches on the plate then they will show up when used as a mirror.
