Daripada pasirnya diekspor ke Singapore untuk memperluas negaranya, lebih 
baik digunakan bagi mencerdaskan bangsa Indonesia.

Semoga berjaya Indonesia.

Menanggapi rengekan anak saya yang masih duduk dibangku SD untuk dibuatkan
mainan jam pasir, memaksa saya untuk cari ide memanfaatkan limbah botol
plastik kemasan disekitar dapur! Botol plastik bekas ternyata ketika 
dicari
malah tidak ketemu, padahal biasanya "pabalatak" disekitar dapur atau 
meja.

Ketika didapatkan, besar dan bentuk botolpun berbeda-beda 
bentuknya...namun
untungnya kepalanya sama..dan bertutup ..he..he ini yang penting! Lalu 
atap
tutup saling dirapatkan dengan power glue..tunggu sampai rekat dan
kering..kemudian dilubangi bagian atapnya hingga tembus dengan diameter
3-5mm.

Botol seterusnya diisi pasir kuarsa halus. Pasir ini saya minta dari Lab
Sandbox Prodi Geologi. Pasirnya berasal dari Formasi Ngrayong Jawa Tengah!
Ternyata cukup unik mengamati jam pasir berbeda bejana, selain eksperiman
waktu "menggelontor"nya dan pengendapan pasir, bisa nampak juga bagaimana
kelakuan aliran pasir di bidang miring dan berliku-liku.

Selain kita bisa amati juga "mini subsidence" atau amblesan dari berbagai
sudut jatuhnya pasir..Nah sementara ini durasi jam pasirnya sekitar 5 
menit,
lumayanlah buat disiplin waktu baca koran dan "facebook" an..!

Pada attachment adalah foto JAM PASIR NGRAYONG Mungkin bisa dibikin 
durasinya
100 harian, lumayan buat pantau kabinet ESBEYE..
