How to make your own jellyfish: 

Fill water bottle with water, add a few drops of blue food coloring and shake. Set a side.

Make Jellyfish:

Flatten out the bag and cut the handles off.

Cut along both sides of the bag to make 2 plastic sheets. Using ONE of these sheets, fold the center of it into something that resembles a tiny balloon – this will be the jellyfish head – and tie it with thread. Do not tie it very tight, as you need a small hole to pour some water in the head part later.

The rest of the bag will become tentacles. To do this, cut from the edge up to the head – this does not need to be neat. You’ll have 8-10 of these.

For each of them, cut again into 3-4 small strings, and cut off the remaining part. Trim to make random long and short tentacles. Don’t make to many tentacles or it will not float.

Turn Jellyfish over blow air into hole to fill it up. Add water so head is about half full with water and air. You must leave some air inside so it is able to float up. Twist head tight.

Stuff your jellyfish and tentacles in the bottle and screw on the cap tight.

And voila! Let your children flip the bottle upside down and watch the jellyfish swim around.

About the Author: Yvonne Wonder

As the founder and managing director of Destination Sitters, LLC, a national hotel and event babysitting service, and the mother of two children, I strongly believe that family comes first. I personally needed babysitting when I moved to San Diego 14 years ago. Like most parents, I assumed there were standards for temporary babysitting; in reality, there are no state standards or licensing requirements for temporary babysitting. The idea for Destination Sitters was born! I wanted to Give Parents Peace of Mind® when traveling with their children, so I created strict screening requirements for the sitters we refer. There is nothing like the peace of mind that comes from getting great professional help to care for your children, especially when traveling away from home. I and my partners, along with our office staff, have that one goal in mind with everything we do. Through the years of working with children, I have been inspired to write three books, and this blog for parents’ and children’s wellbeing. I believe the best way to teach a child is leading by example, with love, honesty, integrity, compassion, perseverance, and personal responsibility. Learning these values and teaching children that all women and men are equal will encourage them to dream big to be anything they want to be! An entrepreneur for over 35 years, I previously spent years running a construction and design company with two offices in California and built million-dollar estates and remodeled existing ones. For three and half years, I was one of the primary designers on HGTV’s Curb Appeal. I have also been published in books, magazines and newspapers, and have been a featured designer in multiple showcase houses.
