These sound neat and would be really cool IF they grew big as described. However, these barely grow. Most people that got one agreed that they are not worth buying. They make a nice gag gift but growth is so small it takes the fun away.

These would be really cool if they actually expanded to the advertised size. It did double in length, but the thickness stayed almost the same. so they are difficult to see.
