Let's get in Roman Style!
Today we would be making some Pillars which would be a decor for our Aquarium!
Some Simple and easy to get Materials which had cost below $3 for me !
These Look Great in your Aquarium and your could even make a full Scene of Rome by making different castings from cardboard.!

Warning Before Attempting: These pillars are made of Portland cement and Portland cement changes the pH of water, I suggest to keep only hard fishes ( Like Cichlids) for some 3-4 months in the tank in which these decor are kept . Wait Until all pH in the cement is little down to keep soft water fishes in that tank . Other than this you can also keep the casted pillar in tub full of water for 3-4 months with regular water changes!
The Above Picture of pillar was kept in my Aquarium for some seconds only to click a picture and show how beautiful they are! :)
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Let's Start!
Gather all the Right Materials :
1) Cardboard ( which have groves in between for strength ) ( Could be procured from cardboard containers of Air conditioners / Other Appliance Boxes )
2) White Portland cement is a must, to make pillars white! :P
3) Cello Tape / Duct Tape
Step 2: Removing the Upper Layer.
Start by Removing the Upper Layer of Cardboard.
( My Cardboard was Having 2 Layers ,Just Remember to remove layers until you get the groves.)
There would be an Upper Layer under which there are groves
To make the cardboard soft , you may need to remove the other side layer too!
( Just to make it soft and roll it )
Step 3: Roll the Cardboard
So , As we all know .. We are making a pillar and Pillar would be cylindrical shape.
Diameter and Length could be any of your like!
Make Sure to tape the whole roll with cello tape / duct tape.
This Holds the cardboard when wet mixture of portland cement is added.
Step 4: Tape the Roll to a Plastic Base
Now , We Would be taping the Roll to a plastic base , as portland cement would not stick to plastic when dry.
Do Remember to Tape the roll firmly to the base because the mixture might leak if there is a big gap.
Step 5: Make & Pour the Mixture
Make the Mixture a little bit thick and pour in in the cylinder.
Step 6: Remove Tape From Cardboard
Now after 5 Hrs. of Drying , Remove the tape because cardboard would have been wet and needs to be dried!
Cardboard might feel sticky at this time :P
Step 7: Remove the Cardboard
Now you could remove the cardboard by hand.
Step 8: Leave It in a Tub for 2 Days
Fill a small tube with water and submerge the pillar .
Leave it for 2 Days .
This would not affect the pH of the Pillar but it would help it to Remove Powder which is given out by portland cement time by time!
Step 9: Optional: Coat It With Aquarium Safe Silicone
And if you want it to put it inside your Aquarium Immediatly , then you could use Aquarium safe silicone and coat it with a painting brush on the pillar,
This might give a glossy finish which i don't like..
Decision is up to you only.. :)
Step 10: Show It to Your Friends...
Guaranteed your friends would appreciate your work and beautiful thing created by you...
