The Best Sensory Play Kits for Kids

Play is at the core of learning during the early years and it can take many forms. One of the most important of these is sensory play because it engages all of a child’s senses (taste, touch, smell, sight and hearing) and has a enoumous positive impact on brain development.

Our Sensory Play Kits are a fun and easy way to keep your child engaged while at the same time capitalizing on the benefits of sensory play to nurture their mind!

If it’s too stiff, add a small amount of water. If it is too watery add more baking soda and mix. Make sure your paste is not too watery as it will be harder to create the sun. When the paste is placed in the sensory bin it will start to spread out. If it is too watery your sun will change its shape before your little one can make it fizzy.

Make the Sun

Take your spoon and start to create the sun in your sensory bin by spooning out a large amount for the center of the sun. Place it in the center of the sensory bin.

Take smaller amount of the paste and create the flares of the sun. Only use a small amount as the paste spreads out as it sits.

Pour some vinegar into a bowl and hand your little one an eye dropper and invite them to squeeze the vinegar onto the summer. It will create a really cool fizzing sound and action as the vinegar reacts with baking soda. The fizz looks like solar flares!

What to Talk About:

Fizzy Sun Sensory Bin: Summer STEAM
  • Discuss the chemical reaction behind the combination of baking soda and vinegar: When you combine baking soda (a base) with vinegar (an acid), it releases a gas (carbon dioxide). Ask them what they see, hear and smell.
  • Ask them what they think will happen when they squeeze the vinegar on the sun. 
  • As they squeeze the vinegar, ask what is happening. Let them describe what it sounds, smells and even feels like, what is happening, what it sounds/looks/feels like, what the solution smells like to them. See whether they can guess what it is.
