Picnic at East Coast Park

What is the best way to celebrate father’s and grandparents day while showing love and care to our community.

The answer are some kisses of sand, sea, scavenger hunt and recycled rocket blaster.

OJS family @ UBI gathered at East Coast Park to have loads of fun and expand the genius inside them by doing a little experiment.

Chemistry Bottle Rocket

What you need:

  • Plastic bottle

  • 3 pencils (unsharpened is best)

  • Duct/ Electrical tape

  • A cork that fits the soda bottle

  • Paper towels

  • Baking soda

  • Vinegar


  1. Build a stand for the rocket by attaching 3 pencils on the plastic bottle

  2. Make a baking soda packet using a paper towel

  3. Pour about 200 ml of vinegar in the plastic bottle

  4. After pouring in the vinegar, quickly push in the baking soda packet and then push in the cork. Turn the bottle over and wait for it to launch! It can take up to 30 seconds.

  5. Be careful of pushing in the cork too tightly

Everyone had a wonderful time indeed, cheers to all the fathers and grandparents!!!!!
