Quirky Adventures

Let us get exploring with three fun activities that are each unique and special in their own way. We’ll see how colors mix through capillary action , how pressure can act as a fun tool to move toys and how we can make a simple yet exciting projector to play with ! Let’s get exploring !

Rainbow Ride

How do we see a beautiful transition of colors when we look at a rainbow ?  Let’s make a unique color mixing station and find out !

What you need :

Tissue papers , water soluble colors ( Red , blue , green ) , 3 glasses , water

How to do it :

  1. Fill water halfway full in each glass and arrange them in a line .
  2. Add a different color to each glass and mix it well .
  3. Now fold each tissue paper into a long rectangle and dip its ends in 2 glasses to form a bridge between the two .
  4. Repeat the same to form a tissue paper bridge for the next 2 glasses
  5. Wait a few minutes and observe what happens !

What happened there :

As the tissue paper begins to absorb the colored water it rises up the length of the tissue due to capillary action. The speed of absorption is same on both sides and thus they meet halfway up the tissue bridge. Since the water is coloured the mixing of colors takes place at this point and we see a beautiful spectrum of colors throughout the setup !

What  happened there : 

Plants need proper conditions to grow which include soil, water, sunlight and air. We often ignore the importance of the right soil for plants. 

Soil plays an important role in :

NUTRIENT UPTAKE: The nutrients need to be held in soil for the plant to pick 

WATER HOLDING: The soil needs to hold adequate moisture to help seeds to grow and also not a lot of moisture because excess water leads to fungal growth. 

MICROBIAL GROWTH: A soil needs to have the proper amount of elements that can allow required microbial growth which will further breakdown fertilizers for our plants to take up and grow better easily. 

Now we used three different soil compositions: 

Sand- has least water holding and nutrient holding capacity 

Soil- absolutely good water and nutrient holding 

Soil with salt- The salt will hold water and make it unavailable for plants to absorb. Also, excess salt will take water from the plant and make it shrink. 

Tube projector

Why do we only get to watch movies on projectors? Let’s make a fun projector  that lets us project whatever we want on a wall !

What you need :

Empty cardboard tube , Cling wrap or a transparent plastic sheet , marker , tape , flashlight. 

How to do it :

  1. Cut out a small area of cling wrap larger than the diameter of the cardboard tube and wrap it over one end so that it covers the open end. Secure with  tape .
  2. Using a marker, draw a letter or an emoticon on the outside of the cling wrap. Make sure the lines are thick.
  3. Now in a dim area turn on the flashlight and point it inside the tube from the other open end . Face the tube towards a wall and now you will see a projection of your drawing !

What happened there :

The flashlight is our source of light and the drawing on the cling wrap acts as an opaque object in its path.  Light cannot pass through that particular region so when you see the project on the wall you are able to see a circle of light with a shadow region of the drawing. This explores the property of light traveling in a straight line !

You can switch the cling wrap and keep drawing new and fun pictures to project with your tube projector !

Crawling spider

Let us dive into making a crafty spider that can crawl up her web when we ask her too !

What you need :

A4 sheet , colors , straw , Scissors , 50 cm thread , tape / glue .

How to do it :

  1. Draw a funky spider on your A4 sheet and color it in. Cut it out using the scissors.
  2. Cut 2 pieces from the length of the straw, of equal length ( at least 4 cm long ) .
  3. Paste these 2 pieces on the back of the spider using tape such that they are parallel to each other and at a distance of 2 cm from each other. Paste them towards the center .
  4. Place your thread like an upside down letter ‘ U ‘ and pass the two ends through the straws . Tie a knot at both ends to prevent the spider from slipping off .
  5. Now hang the thread from a hook or hanger keeping the spider at the base i.e. toward the 2 ends.
  6. Now lift the threads a little towards you and pull the ends in opposite directions . The spider starts to move up the string ! You can also pull the threads  one at a time making sure they’re pulled away from each other .

What happened there :

The tension in the string causes the spider to move away from a tense area. It acts like a push to the straw and since the upper portion of the thread is at ease the straws jerk upwards towards less tense areas. This cycle continues as we keep pulling the thread and the straws keep seeking less tense regions.

Today’s activities were surely off the track and we hope you had fun creating quirky toys today ! See you on the next adventure!
