Using clean spice jars I tried three different designs for stars in jars. None of them was particularly great, but I could imagine kids being at least semi-satisfied with the results. I'll list them in order of most toddler-friendly to least;
- Cut plastic star garlands into pieces the length of the jar. Using tape, stick the ends of each garland to the underside of the lid or inside the jar's rim-top. Screw the lid on.
- Push a rubber animal or toy into a jar (it's helpful if it's flexible and slightly wider than the jar so you can get it in, and it will hold itself up mid-jar), I used the decoration off a novelty bendy straw. Pour water in almost to the top. Add some glitter and stars. Screw lid on tightly and shake gently.
- Pour watered down glue into a jar. Add some glitter and foil stars, and gently roll the jar so that the glue coats the inside of the jar and the stars and glitter stick. Leave to dry overnight. Find a tiny toy, and put a sticky-dot on it's base. Using long tweezers, push the toy inside and hard against the base of the jar. (Mine fell over but with a push with a pencil-end got back in place.) Screw the lid on and enjoy.
