Hi All,

I wanted to introduce liquid density concept for my son and have fun

I am going to share how to build Ocean in a bottle and Oil Timer, using everyday items, found at home

Kids can do this by themselves with little Adult supervision and have fun

Step 1: Oil Timer

Material Needed

  • 2 Plastic bottles ( small sized, cola bottles)
  • 1 Straw or thin pipe
  • Super glue
  • Water ( Distilled water prefered )
  • Blue Water color
  • Vegetable oil

How to make ?

  • Super glue two bottle caps and puncture/drill holes large enough for the pipe to pass
  • The pipes must fit tight, if you feel they are loose use can use super glue to hold them
  • The pipe height is adjusted as per the image ( It should not be at same height, keep 0.5 inch gap)
  • Add water to one of the bottles and add (water based) blue color in it, till you are happy with the shade
  • Close the cap while applying super glue
  • FIll Oil into another bottle, till the rim edge

Step 3: Tips

I noticed after a day playing with them, the clarity in the oil went bad. This was because of impurities in water that got emulsified in oil.Let the bottles sit for a day, all dirt / impurities settle as a small layer just above water and below oil

Carefully remove oil and then water using a straw or pipe and fill them up again
