With a straw and a scissors make this FUN SPIRAL.
Hold the straw in one hand and start cutting a spiral with the other hand.
For this you will need to keep rotating the straw with one hand and cutting with the other.
Keep cutting until you cut the spiral on half the straw.
Now stretch to see the spring like spiral.
Now flatten and cut a pencil point on the other end to make a REED.
Take a spiral straw without the reed.
On blowing the spring will flagellate and vibrate like a baby elephant’s trunk.
Now blow the one with the REED.
This is a two-in-one. You will see the vibrating straw as well hear the flute!
