    • measuring cups and spoons 
    • bowls 
Slime with stuff in it (liquid starch)
  • Recipe:
    • 1/2 cup glue, 1/2 cup liquid starch
    • Add liquid starch by the tablespoon until the mixture is no longer stringy and does not stick to the sides of the bowl
    • Knead
    • Add pompoms, sand, or other ingredients and knead to mix thoroughly
    • Too sticky? Add starch. Too slimy? Add glue.
  • Supplies
    • glue
    • liquid starch
    • food coloring or paint, pompoms
    • measuring cups and spoons
    • bowls
Soap Foam Dough
I got this from And Next Comes L. I had a little trouble finding enough foaming hand soap and ended up using some antibacterial stuff as well.
  • Large plastic tubs, aprons, baby wipes, sink, paper towels, plastic tablecloths
  • Measuring cups and spoons
  • Foaming hand soap
  • Corn starch
  • Watercolors
No Bake Playdough
I just grabbed this recipe off the internet here
  • Large plastic tubs, aprons, baby wipes, sink, paper towels, plastic tablecloths
  • Measuring cups and spoons
  • Flour, oil, salt
  • Food coloring
Other Supplies
  • sink, paper towels, cloth towels
  • ziplock baggies
Other Slimes
Polka Dot Slime
Color-changing slime
Sand slime
Extra projects
Many of these can only have a few kids at a time working on them, so I have other art materials out. They can create a volcano with books on display, do sticker art, or draw and write about their experiments.
  • Handmade paper (donated)
  • Recycled cardstock
  • Stickers and colored tape
  • Markers, glue, scissors, staples, tape
  • Sidewalk chalk (for outside programs)
Evaluation
  • 3-13-18
    • Attendance: 36
    • Notes: We just did marshmallows this time around. Marshmallows and Peeps. The kids were perfectly happy eating, melting, rinse and repeat.
  • 4-20-17
    • Attendance: 45
    • Notes: I've done this once before but I didn't take any notes so I basically recreated this from scratch. I think last year I had starbursts and more taffy-like candy - that has more interesting melts. It felt like hardly anyone came, but it's one of those programs where people only come for a little while.
  • 2-26-17
    • Attendance: 36
    • Notes: I ran out of stuff and grabbed the pectin from the last program, forgetting that it sticketh closer than a....well, a sticky substance. Note to self NO PECTIN EVER AGAIN. Also, you need foam for the soap foam dough, so next time get dispensers! We could happily have mixed things for twice as long though and everyone had fun.
  • 10-13-16 (popcorn science)
    • Attendance: 50
    • Notes: Nobody really does science, they just POP ALL THE CORN. We went through 3 bags of white popcorn, a bottle of yellow popcorn, and several cobs of ornamental corn (it generally smokes and does not pop well. I explain to the kids that this is science.). This program does take some cleaning up as popcorn gets everywhere.
  • 9-22-16 (bubbles)
    • Attendance: 30
    • Notes: It was hot and humid and there were gnats. Mostly little kids who just enjoyed spraying bubbles everywhere.
  • 6-30-16 (slime)
    • Attendance: 60ish?
    • Notes: We did 3 different kinds of slime. The color-changing slime is too expensive for everyone to do - my aide demo'd it. The polka-dot slime is very messy and requires a lot of patience. It was fun to do once, I wouldn't do them regularly though.
  • 3-10-16 (candy/lava lamp)
    • Attendance: 50
    • Notes: There was a lot of candy.
  • 10-15-15 (slime)
    • Attendance: 55
    • Notes: I had just finished jury duty and was too exhausted to really do anything. My aide and an associate from another department mostly ran it. We just did slime (adding glitter) and tape art while we were waiting our turn.
  • 3-12-15
    • Attendance: 30
    • Feedback/Connections: The bulk of today's attendees were middle schoolers and they had a great time.
    • Notes: I don't technically do liquid rainbows - we dripped things in to see what would happen and then I let the last couple middle schoolers dump everything together.
  • 2-19-15 (volcanoes)
    • Attendance: 26
    • Notes: To make sure I had enough ingredients, I planned to set off volcanoes at 3:45, 4:15, 4:45, and 5:15 (more or less) instead of doing them constantly and giving each kid their own volcano. I only ended up needing to do two - it was freezing cold and we had a very small group and making the dough was very absorbing and time-consuming. I thought at the last minute that I should use my big half-gallon water bottles and they were perfect - we fit 8 into one swimming pool and didn't have to use a second pool at all.
  • 3-13-14 (volcanoes and slime)
    • Notes: I was going to have a third project, liquid rainbows, but then realized that while I'd gotten the ingredients...I didn't have anything to pour them into! So that will be a project for another time. This was enough anyways. MORE than enough. I covered the tables for the slime and we did the baking soda volcanoes in the swimming pools, lined with plastic tablecloths. I should definitely have covered the floor with plastic - we got a lot of dough on the floor and that took my aides a while to clean up. I also needed more specific recipes for them. One was in charge of the slime and the other in charge of the dough and I did the actual pouring of the volcanoes (although the kids added the "magic ingredient"). At the last minute, I added markers and paper for the people waiting their turn and that was genius - the kids loved it. It was one of those programs that whizzes by - we actually stopped around 4:40ish when we started running out of ingredients for the dough and we were all exhausted!
