Size is as-packaged, or the diameter of loose marbles. ("D" is the diameter of round items other than marbles.)
Grow Jelly marbles from tiny water bead babies with this fun kit! Submerge the beads in water and they immediately begin to grow! After about a day they are the size of large marbles - hundreds of times the size of the beads! (They are slimy, but not sticky!) Leave your marbles out to dry, and they become tiny beads once again! This kit contains a baby soda bottle, water beads babies and a flyer with fun activities and experiments you can do with your marbles and baby soda bottle. We also sell loose baby soda bottles if you want to buy more of the tubes only.
These are also great on Halloween - prepare them the day before and they feel like a bowl of wet, squishy eyeballs!
These are actually so cool. I wasn't expecting them to distract my boys for as long as they have, and I admit I had a lot of fun with them too. A little messy but not in the traditional sense, they don't stain anything the beads are just tiny and can easily get lost if your kids are a little wild lol... not sure how long they will last when used repeatedly.
