CHEMISTRY Super Thirsty Molecules! Instant Expanding Snow What a blizzard! You’ll be amazed - add water and the powder will EXPAND 40 times in volume before your eyes to produce fluffy, dry, white snow. As used in the filming industry. And the best: Prepared snow will shrink in days and expand again with water. Safe, non-toxic, and biodegradable. Age: 6+ Warning: Slippery when wet. Single Pack M12 A$ 4.00 (makes 700 ml snow) Contents: Instant snow polymer, measuring cup, spoon and instructions. School Lab Pack M13 A$ 27.00 (makes 6.6 liters snow) Enough powder so that 20 students can produce at least 330ml snow each. Contents: Instant snow powder (80g) ; plastic cups (25); measuring spoon (5); instruction sheet and science info. Snow Refill Pack 80g M13R A$ 22.00 Snow Bulk 350g M06M A$ 72.00 Snow Bulk 500g M06L A$ 89.00 Instant Wet Snow Prepare instant wet, shiny and sparkling snow from powder and water, ideal for outdoor fun. The snow powder is added to water and stirred to form a clear gel and fluffs up into snow on stirring. Can be coloured with food dye. Snow can not melt but will shrink when water evaporates and expand again when water is added. Included: Instant snow polymer and instructions. Safe, non-toxic and bio degradable. Age: 6+ Warning: Very slippery. Super Slurper The same powder found in disposable baby nappies will teach osmosis and super absorbance instantly. You can simply reverse the process by sprinkling table salt on the gel. Age: 6+ M14 A$ 12.00 (100g) M14L A$ 28.75 (400g) Slippery! M24S 200ml A$ 9.00 (Makes 13 liters) M24L 1200ml A$ 39.00 (Makes 80 liters) Now absorbs 400 times its mass in water at a great speed! VIDEO VIDEO ONLINE ONLINE Turn water into gel instantly!

CHEMISTRY Expanding Cubes and Spheres Super absorbent polymers absorb large volumes of water when placed in water and are turned into hydro gels. The volume change can be an incredible 250x of the original volume and is fully reversible. The gelled polymer contains up to 95% water so it has the same optical density as water and becomes invisible in water . . . VIDEO ONLINE Expanding Spheres (Gigantic) This is the most amazing absorption demonstration we have experienced! Grow gigantic water spheres in hours! Pop the 15 mm soft spheres in water and in 48 - 72 hours (2 - 3 days) you will have gigantic water gel spheres up to 77 mm in diameter! And as they contain 98% water, the clear spheres will be invisible in water. Add food colouring to the water (3 drops per 250 ml water) to produce coloured water spheres. Leave them out of the water and they’ll shrink back to the original size, then recycle them by expanding in water again. They make great decorations in flower vases but no one can resist the amazing slippery gel feel! Age: 6+ with adult supervision. M45 A$ 8.00 (~25 spheres) Expanding Spheres (Large) Amazing water spheres! Pop these 3.3 mm rock-hard spheres in water and within hours you will have 20 mm jelly-like spheres! That’s a 220 times increase in volume! Leave them out of the water and they return to the original hard spheres. Then expand them over and over. Bounce, roll or squeeze them or germinate seeds amongst them. Loads of gelled fun! Available in clear, red, green or blue. Please indicate your choice. Age: 6+ with adult supervision. M46 A$ 7.00 (~500 spheres) Expanding Cubes These tiny gel-like cubes will expand dramatically when dropped in water. After a few hours you will have large gel-like cubes that are invisible in water. Or add food colouring to the water to produce coloured cubes. Leave them out on the shelf and they become small cubes. Can be expanded many times into irresistible, slippery giant jelly cubes. Age: 6+ with adult supervision. M47 A$ 7.00 (~100 cubes) Expands to 77mm! New! Safety: Made from non-toxic super absorbent material, these spheres are safe & fascinating to touch but due to the small size are NOT classified as TOYS. We recommend adult supervision. Super Expanding Crocodile Experience the exceptional growth of creatures in water to more than 27 times their original mass. (Our crocodile increased from 77g to 1640g in a month!) Integrate math and science classes by making students graph and investigate the growth of these creatures in length, width, mass and volume. Then reverse the process by evaporating the water and make the creatures return to almost their original size. Please note: It takes 3 to 4 weeks to fully expand. Age: 7+ or as a demonstration for younger students. M16C Crocodile A$ 5.75 Super thirsty croc! 77g 1640g Prices include GST more products & descriptions online 9
