Giant Soap Bubble Experiment

Get your child excited about summer with this fun science experiment! After some measuring and mixing, head outside and run around to create some seriously giant bubbles.

Let’s make some bubbles!

Roll up your sleeves for this fun science experiment. This activity is broken into two parts. First, gather some ingredients and have your child help you create your bubble mixture. Then, set it aside to do part two and create your bubble wand with some straws and string. The straws will be used as handles and the string will help create the bubble and hold the mixture. Have fun!  

☀️Messy alert! This activity is best done outside while enjoying a warm, sunny day!
