Unfortunately, the type of mold pictured with this description are not of the quality I purchased in past years. The instructions didn't say to do this, but there looked to be some fairly large gaps which I feared would mean the ball didn't hold together well. I blogged before about cleaning some two pence coins with vinegar , and how they got a turquoise tinge after washing if we didn't rinse off the cleaning solution.

This Crystalverse Kiki Mini Kit introduces a cool, cosmic character, perfect for creative kids with big imaginations! This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below. The Dinosaur Colour-In Foam Magnet Kit bring you the perfect project for getting creative with colouring! The kit can be used to reinforce students' mastery of lab procedures, as an unforgettable introduction to polymers, or even as an energy lab (measuring bounce heights). You may get hours of fun playing with your creation but certainly not when creating them as they don’t take long to make and the 3 left over bags wont go that far.With just a little water, you'll be able to create a fun toy that'll give you endless entertainment. Once the gaps are filled, the polymers start to expand again, releasing the energy they absorbed and making the ball bounce. A great gift idea for space fanatics, this NASA Make Your Own Planet Bouncy Balls set is sure to be a hit. This was definitely a fun way to introduce polymers to my son, and the bouncy ball will hopefully last a while! An ideal craft idea to get stuck into on rainy days or in the school holidays, kids will love making and designing their own bouncy balls.

place in a glass of water for two minutes, remove let stand for a further 2 minutes before removing from the mould, rinsing and leaving to dry.The mad scientists behind Crazy Aaron's Thinking Putty have created PermaPutty, a new formula that combines with the included activator compound to transform into a permanent bouncy ball in just ten minutes! Creative kids can opt for funky patterns, draw on a message or perhaps a face or name, whatever they decide - it’s a whole new ball game!

We'd seen some malachite on a recent visit to the Natural History Museum, and admired its lovely green/blue colour. A mixture of up to five colours can be poured into one of the three supplied moulds (one large, spherical design and two small, irregularly shaped ones), immersed in water, and then split open after four minutes to reveal a superbly bouncy creation. Students can use the Polymers and molds to plan and conduct an investigation to describe and classify different kinds of materials by their observable properties. Easy And fun to make My 7 year old daughter bought this with her pocket money and couldn’t wait to get home and make some bouncy balls, with the help of her 10 year old brother it kept them entertained for a couple of hours experimenting with ways to make the balls.Students can gain firsthand experience with polymers and learn more about synthetic materials and where they come from. The Bee Pom Pom Plate Kit shows you how you can create a fun, quirky design with a few simple craft materials!
