Good morning steemians. It's a pleasure being part of this community where one can share his or her own skills for others to learn. Today, I want to share my first two skills and I'm sure you'll be fascinated to know how this works. I'll first start with the general knowledge. I want to show you that light passes through a straight line using this simple experiment.

Light passes through a straight line. How?

Apparatus used for experiment

• candle
• matches
• Cardboards as Screens
• Folded cardboard paper in place of string
• Gum or cellotape.

Aim of the experiment
Every experiment has aims and the aim of this one is to show that light passes through a straight line.

Methods of carrying out experiment

• Step 1: Take out your cardboard paper and carve out 3 squares of considerable and equal height and size. Create an opening at the center of these 3 cardboards called screens.

• Step 2: Cut a piece of the cardboard to be long and medium in size. Then fold it together and tie a cellotape around it. Ensure that the opening in the folded cardboard is not to big.

• Step 3: Place the folded cardboard at the center of each Screens holes you created and give each screen some spacing. Glue the screens on a material and make sure the folded piece you put at the center must protrude at one end of the screen.

• Step 4: At the end of the screen where the folded piece protrudes, you place a candle of equal height with the folded paper when viewed from below and then ignite it. Make sure the flame of fire is at the center of the opening in the folded piece.

• Step 5: After ignition, you look at the other end of the screen and check if you can see the candle light and rays. If you can, then light passes through a straight line and this supports Rectilinear propagation of light

Do you know how to knot a tie on your own?

I'm gonna teach you how to knot a time under 45 seconds. Follow the pictures for steps.

  You twist the other side of the tie twice until it meets the enlarged part of the time.

• Step 5
  The opening in the small part should be joined with the opening in the big dude without losing guard.
  

• Step 6
  The part of tie that is still stretched when joining the openings should be put in the middle of the holes. Ensure you don't let go of the holes. Use one hand for the holes and the other for put the stretched part into the holes. After that, you hold the tip of the tie you put in the holes and the head and drag them at once.
