Jikken Slime Jelly — Stretchy Science Jelly Kit

A candy kit built like a school science experiment. Add water, keep stirring, and the mixture runs through three visible changes before it turns into a soda-flavour jelly that stretches further the more you work it.

What happens

• 1 — it changes colour. The mixture turns as you stir
• 2 — it foams. Bubbles rise through it like a reaction in a beaker
• 3 — it stretches. The finished jelly pulls out into long slime strands — see how far you can get it to go

Soda flavour, no fruit juice. Water only, no microwave and no stove. One pack makes one tray's worth.

If you already have our Kracie W Slime Jelly, this is the same idea done differently: that one is two slimes you combine, this one is a single slime that transforms in stages while you watch.

Made by Meiji Chewing Gum in Japan and posted from our shop in Tokyo. The packaging is in Japanese — our English instructions library covers the kits in this range.
