Question

Make a small list of the precautions that you had to take  while performing this water balloon fountain experiment​

Answer 1

Answer:

1.  Do this activity somewhere you can make a watery mess, such as a sink or outside.

Explanation:

             2.  Make a small hole about 10 cm up the side of the plastic bottle. The hole should be about the size of the straw's diameter. This is a little tricky, so ask an adult to help. We carefully used the point of a pair of scissors, gently rotating it on the plastic until a hole broke through.

3.  Place the straw into this hole so it is half inside the bottle and half out. Angle it so the outside end points upwards.

4.  Press adhesive putty around the straw on the outside of the bottle to minimise leakage from the hole. Try and make a good seal.

5.  Fill the bottle halfway with water and add a drop of food colouring.

6.  Does the water come out the straw?

7.  Blow up the balloon. Keep the air inside the balloon while you stretch the balloon ends over the top of the bottle.

8.  Hold the balloon in place, then release the air into the bottle. Watch what happens as the balloon deflates.
