Easy discovery bottles with a science theme! The possibilities are endless and I have so many here for you to try. Here’s a few simple ones to get you started. Hope you enjoy!

What are discovery bottles?
Scientific bottles or discovery bottles allow kids of multiple ages to enjoy exploring easy science concepts together! Plus plastic science bottles are great to leave out in a basket at a science center at home or school. Sit down on the floor with young kids and allow them to roll them gently around.
TIP: You can tape or glue caps if needed!
Yes, I have used glass jars and I made sure to supervise my son closely. Please use plastic if that is best for you! We have started using the VOSS plastic water bottles for our discovery bottles and really enjoy them!
