Once Upon a STEM
When can you introduce a child to STEM? Once Upon a STEM allows even the earliest of learners to build successfully with this collection of big, soft, and colorful magnetic foam construction pieces. The frustration-free Once Upon a STEM blocks are designed with a patented magnetic connection system that ensures these blocks always attract, with no polarity conflict. The non-toxic and durable Once Upon a STEM blocks even rotate 360 degrees when connected, expanding their open-ended, multi-sensory possibilities. Because they click when connected and spun, the blocks are also an auditory treat for tiny ears. Not only that, Once Upon a STEM blocks float in the water, making bathtime a creative space for mini-engineers, and providing a distraction for hair washing.

Brilliantly designed, each safely-embedded magnetic connector is flush with the foam surface, so there are no hard protrusions that could cause injury. They are soft, so they won’t hurt if thrown. After the blocks are connected, they stay together firmly, but the magnets are not so strong that your toddler won’t be able to pull them apart.

Encouraging tactile and sensory development, Once Upon a STEM blocks exceed all international testing standards for safety. Your toddler can play with them inside, outside, in the pool, at a campsite, or just about anywhere he feels inspired to create. When they get a bit grimy, toss the blocks into the dishwasher to wash with your dishes or spritz them with a bit of bleach spray, and they’ll be sanitized and as good as new!

With Once Upon a STEM, Toddlers can learn about stacking, color, and shape recognition, in addition to developing rudimentary construction and engineering skills. Built to inspire whimsical play, the vibrant colors, soft and smooth finish, and straightforward design of Once Upon a Stem make it stand out from short-lived playthings.

Once Upon a Stem includes 48 blocks in 15 shapes, with wheels to get those creations moving. Once Upon a STEM also includes a durable, lightweight zippered mesh tote, perfect for wet or dry storage.

Unlike other toddler toys, Once Upon a STEM is made to be enjoyed for years. Still, if your family should ever outgrow them, the manufacturer will welcome them back. They will sanitize used blocks and donate them to a happy home.

Wow! Our toddlers love these!

We have two 16 month old toddlers and they love these! They can use their fine and gross motor skills to build without the frustration of having their creations fall down. Livingroom, dining room, bath time, anytime these are a hit! After tubbie time we hang them in a mesh bag to dry. We've had no problem with rusting.

Our favorites so far!

These are the most amazing building blocks. I was hesitant to get them as we have other kinds of building blocks in ur house but these have been amazing for my 2 year old and honestly everyone in the house loves to play with them! She feels empowered to try new things and discover without frustration that other blocks can bring while learning fine motor skills. Highly recommend!


My child likes to pull the pieces apart. He's not quite to the point where he will try to build anything. I'm hesitant to put anymore pieces in the tub as last time water got in where the magnet lives and rusted it a little. I guess all the water didn't evaporate while it was drying. Still works though.

The best toy for toddlers!

This is amazing! My 2 and 4 year old can play with these for a very long time. It is easy for both to build and feel they are creating something. The way they magnetize is almost sensory pleasing. I want more! Must buy. Just do it!!

This is my favorite thing!

These blocks are my favorite thing in the whole kit. My youngest is too young for these, but my 3-year-old loves them and so do I! The magnets make them so easy to use. I like that the are soft, you won't kill your feet if you step on them. My daughter likes that they can go in the bath tub. I wish I had blocks like this when I was a kid.
