Chemistry Car

Chemistry Car is a fun science experiment for kids which show how easily they can design their own Chemistry Car – which works on Newton’s -3rd Law of Motion using materials provided in the Monthly Science Box. Simple step-by-step instructions provided in the box makes the entire construction process much simpler! Once the car is made, the real exciting moment lies while waiting for the cork to detach from the bottle with a blast sound (literally)!  And watch your car move!!

Safety First! Adult Supervision Required, Don’t Eat/Drink your Experiments, wear safety goggles where ever required

Materials and tools required

In the box

  • Funnels
  • Cable tie lock
  • Pepfiz tablets
  • Popsicle
  • Double sided tape
  • Small beaker – 50 mL
  • Black Tape
  • Plastic Bottle with cork
  • Prepared car base

Video on Youtube for the Experiment

What to Do ?

  1. Insert the cable tie lock into the popsicle holes
  2. Fix the plastic bottle between the cable tie and popsicle
  3. Cut the extra length of the cable tie lock
  4. Similarly ,attach another set of popsicle and cable tie lock
  5. Peel off one side of double sided tape and stick it at the back of the popsicle.
  6. Similarly ,stick another strip of double sided tape to the second popsicle
  7. Attach the bottle to the already prepared car base (balloon powered car experiment)
  8. Fill water in a beaker till the brim
  9. Pour the water in the bottle using a funnel
  10. Insert the cork. Make sure it is tightly attached.
  11. Crush a pepfiz tablet into smaller pieces.
  12. Put the broken pepfiz tablets into the bottle quickly. Insert the cork again.
  13. Let the pressure build in the bottle .Keep the car on a flat surface in such a way so that the cork faces a hard surface (we have used the science box. Wait for the cork to detach and watch your car move).

Working Principle of Chemistry Car :

Chemistry car demonstrates motion as well as chemical reactions. This experiment demonstrates Newton’s Third Law of Motion. The law states that: “For every action, there is an equal and opposite reaction.” So when the carbon dioxide gas erupts out of the bottle in one direction (action), the Chemistry car rockets off in the opposite direction (reaction)! This gives us the visual experience of Newton’s Third law. Pepfiz tablets generally contain an effervescent powder called sodium bicarbonate as one of the main ingredients, so when these tablets are put inside the bottle, there is a chemical reaction between sodium bicarbonate and water which results in the evolution of carbon dioxide gas. Once there is enough carbon dioxide build up, it pushes the cork out and the car moves in the opposite direction.

To sum it up, the fuel used in this car is pressurized carbon dioxide gas and water, and moves due to Newton’s Third law of motion.
