WORKING MODEL FOR SCIENCE EXHIBITION- DANCING BALLOON

 DANCING BALLOON 

SCIENCE EXHIBITION PROJECT FOR HIGH SCHOOL STUDENTS 

A working model for science exhibition ‘THE DANCING BALLOON’ is an application of Newton’s third law of motion- Every action has an equal and opposite reaction and also explains about effect of less friction helps in the motion of a body.

MATERIALS REQUIRED 

1- Balloon 

2- Compact disk (CD)

3- Glue

4- Bottle cap

PROCEDURE 

*Put a hole on bottle cap(at the centre) 

* Using glue stick the bottle cap at the top of CD (cap should be fixed on rough and non shiny surface of CD . Make sure no gap between CD ad the bottle cap)

* Keep it aside still glue dries up to make strong bond between CD and bottle cap

* Inflate the ballon and fix it on bottle cap as shown in video 

* And keep CD on plane surface and release it.

RESULT

Balloon/CD arrangement start moving around the plain surface automatically .

SCIENTIFIC EXPLANATION 

Due to the force applied by the air inside the balloon it start moves automatically. ( air released through the hole of bottle cap from the balloon apply force on surface then it start moving and also air will act as Film between CD and the surface to reduce friction.
