Clear Worm Goo is finally available in a big 1-liter bottle. Just add a few drops of food coloring to make different colored worms, or try adding a squirt of Pearl Swirl Fluid to make the coolest looking "metal" worms. You'll receive a supply of dry Activator powder that is easily mixed with water to make Worm Activator solution. Okay, we'll toss in a measuring scoop and an empty squirt bottle to get you off on the right foot. Ages 6 and up.

You get enough materials to make about 50 meters (160 ft) of Worms!

This kit was used as one of many science experiments for a birthday party. We had worms of many colors. The kids thought they were gross and cool all at the same time and clammered for more.

so much fun!

I took this kit to a Halloween party. The kids had so much fun. Fat worms, skinny worms, short worms, long worms, worm eggs, you name it, they tried it. I only wish I had remembered a trash bag to lay on the picnic table for easy clean up. Next time I buy these, I'll bring a knife for dissecting.

worm goo!

We used this for our Halloween parties and the kids loved it! They also made monster snot from the GAK experiment from the website. Both were a huge hit! Thank you!!

Love this kit, and so does my class. Fun stuff.

I do have 1 suggestion, though:

I purchased the refill kit after reading that there would be enough "stuff" for a class of 24. After measuring the activator powder with the blue scoop that was included, I actually did not have enough. I was bummed to have too little powder, yet extra goo. Now my kids had to share, versus having their own cup. Would love to have a few extra scoops included in the bag. Just a thought.

Thank you for your products.

Should be 6 stars!

I haved used this activity with my Early Childhood students for years. Its incredibly easy for them to mix and measure it themselves. We mix pearl swirl, color tabs, and the pinch and mix colors into the worm mix to make awesome colors. How someone could rate this beow 5 stars is a mystery to me! These work great!

Worms! Worms! Worms!

We used this at our Children's Ministry booth at our church's Open House (with references to where worms are mentioned in the Bible!) The kids LOVED this activity and went home with oodles and oodles of worms in their baggies. It was very easy to set up and clean up, and we used every last drop. This is a great product!

Great Product

Dear Steve,

My name is Mike AKA Dr. Electro Mad Doctor of Science. I have been performing as a "Mad Scientist" at children's parties here in NJ for the last five years. Thanks to your products it has made my show a big hit. I use your ASAP, instant snow, airzooka (and the megazooka) and worm goo. needless to say the kids love it when I do the instant worm experiment. I use it towards the end of the show when I start to explain polymers. They especially like it when I tell them they can take a piece of it home. When people ask were I get all my cool experiments I tell them to look up Steve Spangler on line and go to his web site. SO many, many thanks for your products and videos. I really enjoy watching the you tube videos. Please let me know if you will be traveling to the NY/NJ area with your workshop I would love to attend one.

Thanks again
Mike

Kids love making their own squishy worms. They make them long and short and can;t get enough of it.
