I found this idea at Childhood Magic and it looked like such good gloopy fun, that I introduced it on a rainy afternoon to entertain Little B. With some tissue paper, balloons and home-made paste (basically flour and glue), we both had good fun putting these together.
After they dried, we put in some fake tea-lights and had some supper via “candle” light.
I’ve even contemplated it as a good party exercise. So this might make a reappearance during this summer for Little B’s fourth birthday :-)
