There's an aspect of science and spirituality that tend to go hand in hand for me... it's part of an "inner child" thing... whereby I like sensory educational toys and the gooier they are, or the more explosive they are, the more I like them...and they tend to do "spiritual stuff" to me as well...so, without further ado, I will list some of them.
1. Water Pearls. I love the texture and colours of these things, and I just found out there's a gun that shoots them...yayness!
2. Crystal growing kits...this will keep me amused for hours on end...and I may look I to growing Bismuth crystals or some more upmarket adult varieties.
I remember the old magic rocks...they were amazing.
3. Kinetic Sand...I could sit there just sculpting this stuff and playing with it for hours.
4. Borax glitter slime kits:
Give me any of the above and I will be amused non stop for weeks...it has the same effect on me as catnip has on a cat...calming, centering, making me peaceful and spiritual....making me go within..and it doesn't take much.
I also remember the moving sand pictures that creates a totally new picture every time you turn it upside down, creating beautiful pyramids everywhere..I would stare at them for hours.
Ooh and I so want the tetrahedron Pocket puzzle cube...
Stuff like this makes me kinda spiritual..
